-
- * Release 2.3.7
-
-2001-10-15 Raph Levien <raph@pixel.artofcode.com>
-
- * art_svp_intersect.c (art_svp_intersect_horiz): Minor
- logic fix so that horiz segments successfully cross
- zero length segments in the active list.
-
- (art_svp_intersect_test_cross): Flags indicating whether to
- do add_point (potentially breaking neighbors) to left and
- to right.
-
- (art_svp_intersect_insert_cross): Provide ART_BREAK_LEFT and
- ART_BREAK_RIGHT flags to art_svp_intersect_test_cross,
- depending on direction of search.
-
- (art_svp_intersect_advance_cursor): Provide flags (allow
- both left and right breaking) to test_cross.
-
-2001-10-15 Raph Levien <raph@pixel.artofcode.com>
-
- * art_svp_intersect.c (CHEAP_SANITYCHECK): Added an inexpensive
- sanitycheck to detect multiple insertions of a segment into the
- horiz list.
-
- (art_svp_writer_rewind_add_point): Avoid breaking lines below
- their bottom point.
-
- (art_svp_intersect_test_cross): Handle cases correctly where
- intersection point matches y0 of left or right segment. These _do_
- happen in real world examples. Also, do add_point on newly
- inserted intersection point.
-
-2001-10-14 Raph Levien <raph@pixel.artofcode.com>
-
- * art_svp_intersect.c (art_svp_intersect_add_point): Fixed
- rather subtle logic bug that misplaced insertion point
- when seg argument was NULL.
-
-2001-10-11 Raph Levien <raph@pixel.artofcode.com>
-
- * art_svp_render_aa.c (art_svp_render_aa_iter_step): Got rid
- of qsort of steps, and now keep the step list in sorted order.
- Further, we combine duplicate steps with the same x value,
- which bounds the size of the step list to x1 - x0, so we
- don't need to dynamically resize it. Thanks greatly to
- Bruce Q. Hammond for the original version of this patch.
-
-2001-10-09 Raph Levien <raph@pixel.artofcode.com>
-
- * art_svp_intersect.c (art_svp_intersect_test_cross): Breaks
- bottom part of line segments in "too close" cases.
-
-2001-10-09 Raph Levien <raph@pixel.artofcode.com>
-
- * art_svp_intersect.c (art_svp_writer_rewind_add_point): Fixed
- bbox computation.
- (art_svp_intersector): Handle degenerate case where input
- SVP has 0 segments.
-
- * art_svp_intersect.h: Moved definition of art_svp_intersector
- inside #ifdef __cplusplus, so it links properly against C++
-
-2001-10-09 Raph Levien <raph@pixel.artofcode.com>
-
- * art_svp_intersect.c (art_svp_intersect_break): Handle
- case when break y equals sweep line correctly. Also adds
- first try at winding number sanitychecker, but that makes
- too many false positives.
-
-2001-10-07 Raph Levien <raph@pixel.artofcode.com>
-
- * art_svp.c (EPSILON): Set to zero if new intersector is
- in use - we want svp's to be in strict sorted order.
-
- * art_svp_intersect.c (art_svp_intersect_test_cross): Explicitly
- check that top points are equal, and swap immediately if b is out
- of order.
- (art_svp_intersect_horiz): Break segments that intersect
- horizontal lines. Now passes "two squares with offset" test.
-
-2001-10-05 Raph Levien <raph@pixel.artofcode.com>
-
- * art_svp_intersect.c: Major changes to accommodate
- horizontal lines. Intersections of horizontal lines
- aren't fully processed, but should work a lot better
- than before.
-
- * testart.c: Minor tweaks. testpat now frees memory
- so it can be run under memprof to detect leaks.
-
-2001-10-03 Raph Levien <raph@pixel.artofcode.com>
-
- * art_svp_intersect.c (art_svp_intersect_advance_cursor):
- Made test_cross for inserted segments common between
- intersection processing and cursor advance, and also took
- care of a case that hadn't been handled before. Also added
- invariant sanitychecker for debugging purposes.
-
-2001-10-02 Raph Levien <raph@pixel.artofcode.com>
-
- * art_svp_ops.c: ART_USE_NEW_INTERSECTOR variants of svp
- ops changed to do shallow free of merged svp.
-
-2001-10-01 Raph Levien <raph@acm.org>
-
- * art_svp_intersect.c:
- * art_svp_intersect.h:
- * Makefile.am:
- * art_misc.h:
- * art_svp_wind.h: First commit of new intersector code. It is
- turned off by default, but can be enabled by #defining
- ART_USE_NEW_INTERSECTOR in art_misc.h.
-
- * art_svp_ops.c: Make svp ops use new intersector if enabled.
-
- * art_svp_vpath_stroke.c: Make vpath stroking use new intersector
- if enabled.
-
- * testart.c: New test case for intersector.

-
- * Version 2.3.5 for the API freeze.
-
-2001-07-12 Darin Adler <darin@bentspoon.com>
-
- * art_affine.c: (art_affine_expansion): Fix handling of
- negative numbers. We ran into this bug a while back when
- figuring out why librsvg couldn't handle certain svg files.
-
-2001-07-12 Darin Adler <darin@bentspoon.com>
-
- * art_misc.h: Change art_expand macro so it's a single
- statement, using the do while (0) trick, which gets rid
- of some warnings.
- * art_pixbuf.c: Add a missing include.
- * art_vpath_svp.c: (art_vpath_from_svp): Initialize a
- variable to avoid a compiler warning.

-2000-08-15 Raph Levien <raph@acm.org>
-
- * art_render.c (art_render_image_solid_negotiate): Only
- sets ART_IMAGE_SOURCE_CAN_COMPOSITE when a compositing
- callback is selected. Previously was causing segfaults on
- non-alpha images. Thanks to Leonard Rosenthol for spotting
- the bug.
-
-Fri Jun 30 22:56:58 2000 Raph Levien <raph@acm.org>
-

-
-Mon May 29 13:48:49 2000 Raph Levien <raph@acm.org>
-
- This is a fairly major commit, as it adds both the new, modular
- rendering architecture and gradients. Quite a bit of the code
- feels like "reference code" now, in that it is (hopefully)
- correct, but not necessarily very fast. In addition, there remain
- a few things not done, including the use of SVP's as non-driver
- mask sources. AlphaGamma and filter level also remain
- unimplemented. No compositing modes other than ART_NORMAL are
- implemented. All in good time!
-
- * configure.in: added -Wmissing-prototypes flag. Bumped version
- number to 2.3.0.
-
- * art_render.h:
- * art_render.c: Added new rendering architecture.

- * art_render_svp.h:
- * art_render_svp.c: Added renderers to use SVP's as mask
- sources in new rendering architecture.
-
- * art_render_gradient.h:

- as image sources in new rendering architecture.
-
- * art_rgba.h:
- * art_rgba.c: Added functions for manipulating and compositing
- RGBA pixels.
-
- * art_svp_wind.c: Added static to trap_epsilon(), #ifdef'd out
- traverse().
-
- * art_uta_ops.c: Added #include "art_uta_ops.h".
-
- * art_uta_rect.c: Added #include "art_uta_rect.h".
-
- * art_uta_svp.h: fixed __ART_UTA_SVP_H__ name.
-
- * art_misc.h: Added ART_GNUC_NORETURN attribute, added that
- to the prototype for art_die(). Added "static" to function
- declarations to avoid warnings when compiled with
-
- * testart.c: Added gradient test.
-
-Thu May 25 23:30:39 2000 Raph Levien <raph@acm.org>
-
- * art_svp_render_aa.h:
- * art_svp_render_aa.c: Added art_svp_render_aa_iter functions,

-
- * art_rgb_pixbuf_affine.h: Put recursive #includes inside
- LIBART_COMPILATION test.
-
- * art_gray_svp.c:
- * art_rgb_svp.c: Explicit casts for callback data. Also removed
- "render the steps into tmpbuf" comment.
-
- * gen_art_config.c:
- * Makefile.am:
- * configure.in: Added code to automatically generate an
- art_config.h file, to be installed in libart's include dir. This
- file defines ART_SIZEOF_{CHAR,SHORT,INT,LONG} and art_u{8,16,32}.
-
- * art_misc.h: Moved definition of art_u8 and art_u32 into
- art_config.h. Added GCC printf format attributes.
-
- * art_svp_wind.c (traverse): Fixed UMR bug here. The function
- isn't actually used, so it's just for cleanliness.
-
-2000-04-18 Lauris Kaplinski <lauris@ariman.ee>
-
- * art_affine.c (art_affine_to_string): Replaced snprinf with
- art_ftoa to avoid localisation of generated numbers
-
-2000-04-18 ERDI Gergo <cactus@cactus.rulez.org>
-
- * art_rgb_pixbuf_affine.h: Included the ArtPixBuf declaration
-
-Fri Apr 14 16:33:55 2000 Raph Levien <raph@acm.org>
-
- * art_svp_wind.c (art_svp_uncross, art_svp_rewind_uncrossed):
- Fixed uninitialized memory reads when inserting new segment into
- active_segs.
-
- * art_bpath.c (art_bpath_affine_transform): Made it avoid
- potential uninitialized memory reads when not all the coordinates
- are needed. Thanks to Morten Welinder for spotting both of these
- problems.
-
-2000-04-05 Raph Levien <raph@gimp.org>
-
- * art_svp_wind.c: Make "colinear" warnings go to stderr instead
- of stdout. Of course, when I finish the new intersector, these
- will go away entirely.
-
-2000-04-04 Raph Levien <raph@gimp.org>
-
- * art_uta_vpath.c (art_uta_add_line): Fixed bug that was causing
- segfaults on alphas. Thanks to msw for localizing it.
-
-2000-01-17 Raph Levien <raph@gimp.org>
-
- * art_svp_vpath_stroke.c (art_svp_vpath_stroke): Typo in api
- header (thanks rak).
-
-2000-01-16 Timur Bakeyev <timur@gnu.org>
-
- * autoconf.sh: Instead of jumping between srdir and builddir just process
- all the auto* staff in srcdir. In fact, just saying the same things in
- other words.
-
-2000-01-10 Elliot Lee <sopwith@redhat.com>
-
- * Makefile.am, *.h: Add rather bad hacks to the header files to allow compilation
-
- * Makefile.am: Distribute libart-config.in
-
-2000-01-09 Raph Levien <raph@gimp.org>
-
- art_rgb_pixbuf_affine.c, art_rgb_rgba_affine.c, art_rgb_svp.c,
- art_svp.c, art_svp_ops.c, art_svp_point.c, art_svp_render_aa.c,

- reading undefined memory (thanks to Morten Welinder).
-
-1999-09-19 Raph Levien <raph@gimp.org>
-
- * art_pixbuf.c (art_pixbuf_duplicate): Added a duplicate function
- at the request of Michael Meeks.
-
-1999-09-11 Raph Levien <raph@gimp.org>
-
- * art_affine.c (art_affine_to_string): Tightened the predicate for
- matching rotate-only affines, which was too weak. Thanks to lewing
- for spotting it!
-
-1999-09-01 Raph Levien <raph@gimp.org>
-
- * art_affine.c, art_alphagamma.c, art_bpath.c, art_gray_svp.c,
- art_misc.c, art_pixbuf.c, art_rect.c, art_rect_svp.c,
- art_rect_uta.c, art_rgb.c, art_rgb_affine.c,
- art_rgb_bitmap_affine.c: Updates to api doc headers.
-
-1999-08-24 Raph Levien <raph@gimp.org>
-
- * art_affine.c, art_alphagamma.c, art_alphagamma.h, art_bpath.c,
- art_bpath.h, art_gray_svp.c, art_misc.c, art_pixbuf.c,
- art_pixbuf.h, art_point.h, art_rect.c, art_rect.h: Added api
- documentation headers.
-
- * testart.c: Added "dash" test, for testing the vpath_dash
- functions.
-
- * art_rgb_pixbuf_affine.h: Fixed the #ifdef for conditional
- inclusion. Thanks to Kristian Hogsberg Kristensen for spotting
- the bug.
-
-1999-08-24 Raph Levien <raph@gimp.org>
-
- * art_svp_render_aa.c (art_svp_render_aa): Added some tests to
- avoid NaN for infinite slopes, which were causing problems on
- Alphas. Closes bug #1966.
-
-1999-08-20 Federico Mena Quintero <federico@redhat.com>
-
- * configure.in: Fixed library's libtool version number.
-
-1999-08-03 Larry Ewing <lewing@gimp.org>
-
- * art_vpath_dash.c (art_vpath_dash): fix a bug/typo that was causing
- certain paths to loop infinitely.
-
-1999-07-28 Raph Levien <raph@gimp.org>
-
- * art_vpath_dash.[ch]: Added a function to add a dash style
- to vpaths. It is tested, but has a couple of rough edges (see
- code for details).
-
- * testart.c: added tests for the new vpath_dash functionality.
-
- * Makefile.am: added art_vpath_dash.[ch] files.
-
-1999-07-26 Raph Levien <raph@gimp.org>
-
- * art_rgb.c (art_rgb_fill_run): fixed incorrect test for

-
-Fri Jul 16 23:42:59 1999 Tim Janik <timj@gtk.org>
-
- * art_affine.c (art_affine_flip): flip translation matrixes as well, by
- inverting matrix[4] if (horz) and inverting matrix[5] if (vert).
-
-Fri Jul 16 23:03:26 1999 Tim Janik <timj@gtk.org>
-
- * art_pixbuf.[hc]: deprecated art_pixbuf_free_shallow(), people should
- always free pixbufs with art_pixbuf_free() and use the _dnotify variants
- for specific destruction behaviour.
- added art_pixbuf_new_rgb_dnotify() and art_pixbuf_new_rgba_dnotify()
- which allow for a destruction notification function. (this involved
- adding two extra pointers to the ArtPixBuf structure, and removal of
- the recently introduced int flags field).
-
-Mon Jul 12 01:13:23 1999 Tim Janik <timj@gtk.org>
-
- * art_affine.[hc]: added art_affine_equal(), which checks two
- matrixes for equality within grid alignment.
-
-Fri Jul 9 17:50:19 1999 Tim Janik <timj@gtk.org>
-
- * art_affine.[hc]: added art_affine_flip() to flip a matrix horizontally
- and/or vertically, or just copy it.
- added art_affine_shear() to setup a shearing matrix.
-
-Tue Jul 6 19:03:39 1999 Tim Janik <timj@gtk.org>
-
- * art_pixbuf.h: added an int flags; member to the end of the
- structure, it currently only holds information about whether the
- pixels member should be freed. (raph: i think flags is more generic
- than free_pixels, so we can reuse that field if further demands popup
- in the future).
-
- * art_pixbuf.c:
- (art_pixbuf_new_const_rgba):
- (art_pixbuf_new_const_rgb): new functions that prevent the pixels
- member from being freed upon art_pixbuf_free ().
- (art_pixbuf_free): only free the pixels member if it is non-NULL and
- the PIXBUF_FLAG_DESTROY_PIXELS is set.
-
-1999-07-02 Raph Levien <raph@gimp.org>
-
- * art_vpath_bpath.c (art_vpath_render_bez): Bad bad uninitialized
- variables.
-
- * configure.in: added compile warnings. Guess why :)
-
-1999-06-28 Raph Levien <raph@gimp.org>
-
- * art_svp_point.h:
- * art_svp_point.c: Added methods for insideness and distance
- testing, very useful for ::point methods in canvas items.
-
- * testart.c: test code to exercise the art_svp_point functions.
-
- * Makefile.am: Additional entries for art_svp_point.
-
-1999-06-28 Raph Levien <raph@gimp.org>
-
- * art_svp_render_aa.c (art_svp_render_aa): Subtle boundary
- case in realloc code -- was causing nasty segfaults.
-
-Wed Jun 23 15:05:43 1999 Raph Levien <raph@gimp.org>
-
- * art_rgb_svp.c (art_rgb_svp_alpha_opaque_callback): Missed a
- case in the anti-segfault crusade. Thanks lewing!
-
-Wed Jun 23 11:16:42 1999 Raph Levien <raph@gimp.org>
-
- * art_rgb_svp.c: Made these routines so they won't segfault even
- if alpha is out of range. Of course, that begs the question of
- fixing the render routines so they won't _make_ alpha go out of
- range, but all in good time.
-
-Fri Jun 18 17:32:34 1999 Raph Levien <raph@acm.org>
-
- * art_vpath_bpath.c (art_bez_path_to_vec): Switched to a new
- adaptive subdivision algorithm, which (finally!) takes flatness
- into account. This should result in both smoother curves and
- faster operation.
-
-Sun Jun 13 21:07:20 1999 Raph Levien <raph@gimp.org>
-
- * art_svp_wind.c (art_svp_rewind_uncrossed): Made the winding
- rule logic even more correct :). I somehow missed the fact that
- a clockwise path should be given a winding number of zero;
- last night's commit tried to make it -1 (which worked for the
- test cases I was using).
-
-Sun Jun 13 01:23:14 1999 Raph Levien <raph@gimp.org>
-
- * art_svp_wind.c (art_svp_rewind_uncrossed): Change to winding
- rule logic so that it correctly handles the case where the
- leftmost segment is negative.
-
- * Makefile.am (libart_lgplinc_HEADERS): made art_svp_wind.h
- a public headerfile. This is needed for the bpath canvas item.
- I'm not sure this is the correct way to do it, but it will do
- for now.
-
- * art_vpath_bpath.h:
- * art_vpath_bpath.c (art_bez_path_to_vec): Added const to arg.
-
- * art_vpath_bpath.h: Embarrassing typo.
-
- * art_bpath.h: Minor tweaks to the #include paths. It is now
- consistent with the other header files.
-
-Wed Jun 9 20:24:45 1999 Raph Levien <raph@gimp.org>
-
- * art_svp_vpath_stroke.c: Added all remaining line join and cap
- types, including round, which takes flatness into account. Several
- new internal functions (art_svp_vpath_stroke_arc) and added
- flatness argument to a few internal functions. I might want to
- change the BEVEL join type to MITER for very small turn angles
- (i.e. within a flatness threshold) for efficiency.
-
- * art_misc.h: Added M_SQRT2 constant.
-
-Wed Jun 2 21:56:30 1999 Raph Levien <raph@gimp.org>
-
- * art_svp_vpath_stroke.c (art_svp_vpath_stroke_raw): Made the
- closed path detection capable of PostScript semantics (i.e. it
- now senses the difference between ART_MOVETO and ART_MOVETO_OPEN).
-
- * art_svp_vpath_stroke.c (art_svp_vpath_stroke_raw): it now
- filters out successive points that are (nearly) coincident. This
- fixes some of the crashes and hangs, including Tim Janik's
- singularity (trying to stroke MOVETO 50, 50; LINETO 50, 50; END).
-
- * art_svp_wind.c (art_svp_rewind_uncrossed): added a test to
- correctly handle empty input svp's.
-
- * art_svp_wind.c (art_svp_uncross): added a test to correctly
- handle empty input svp's.
-
-Sun Jan 17 20:53:40 1999 Jeff Garzik <jgarzik@pobox.com>
-
- * art_affine.c:
- Include string.h for memcpy.
-
- * art_svp_vpath.c:
- Remove conflicting static func definition.
-
- * art_uta_svp.c:
- Include art_vpath_svp.h for func definition.
-
-Mon Jan 4 12:47:47 1999 Raph Levien <raph@acm.org>
-
- * art_bpath.c (art_bpath_affine_transform): Stupid misnaming
- of this function (forgot the "art_").

- * art_affine.c (art_affine_rectilinear): Added this function.
-
- * art_rect.c (art_drect_affine_transform): Corrected the name (it
- was right in the .h). Also made it work with non-rectilinear
- transforms, while I was at it.

-
-Wed Dec 16 14:18:46 1998 Raph Levien <raph@gimp.org>
-
- * art_alphagamma.h:
- * art_alphagamma.c: Added. At present, it only contains a dummy
- stub. When the real code is added, it supports doing alpha
- compositing in a gamma-corrected color space (suppressing
- jaggies).
-
- * art_pixbuf.h:
- * art_pixbuf.c: Added. This is a virtualization layer over
- a few different kinds of image formats.

- generic images over an rgb buffer.
-
- * art_affine.h:
- * art_affine.c (art_affine_expansion): Added this function,
- which reports the exact scale factor in the case of rotation,
- scaling, and transformation (an approximate number in the
- case of shearing or anamorphic distortion).

- * art_rgb_svp.c: Added alphagamma argument (only implemented
- in aa case, not yet alpha case).
-
- * art_vpath.c: increased perturbation to 2e-3, because the old
- value (1e-6) was too small.
-
- * testart.c: added alphagamma.
-
- * Makefile.am: added new files

-
- * art_affine.h:
- * art_affine.c: Added. Everything you ever wanted to do with an
- affine transform. Especially check the functions that generate
- concise PostScript strings for affine transforms.
-
- * art_filterlevel.h: A simple enum for selecting filtering
- style.
-
- * art_rgb_affine.h:
- * art_rgb_affine.c (art_rgb_affine): Added. This function
- composites an (opaque) rgb image over an rgb pixel buffer. At
- present, it's slow and only nearest neighbor filtering is enabled.
-
- * art_rgb_rgba_affine.h:
- * art_rgb_rgba_affine.c: Analogous, but for compositing rgba
- images.
-
- * art_rgb_bitmap_affine.h:
- * art_rgb_bitmap_affine.c: Analogous, but for compositing bitmap
- images.
-
- * art_rgb_affine_private.c (art_rgb_affine_run): Added. This is
- a common function used by all the rgb_affine modules to move
- testing for source image bbox out of the inner loop.
-

-
- * testart.c: exercise the image compositors
-
-Wed Dec 9 23:36:35 1998 Raph Levien <raph@gimp.org>
-
- * art_vpath.c (art_vpath_perturb): Made it deal correctly
- with closed paths (the MOVETO and closing LINETO have to
- agree).
-
- * art_svp_wind.c: Made the bbox calculations for the resulting
- svp's correct.
-
- * art_svp.h:
- * art_svp.c: The art_svp_seg_compare function moved here, because
- it's required in art_svp_ops.
-
- * art_svp.c (art_svp_add_segment): It now does bbox calculations.
-
- * art_svp_ops.h:
- * art_svp_ops.c: Added. Populated with basic union, intersection,
- and diff functions.
-
- * art_vpath_svp.h:

-
-Sun Dec 6 22:15:12 1998 Raph Levien <raph@gimp.org>
-
- * art_svp_wind.[ch], art_svp_vpath_stroke.[ch]: Added, but it
- doesn't work yet. These will do stroke outline and basic
- vector ops like union, intersect, etc.
-
- * art_svp_render_aa.c: Added a simple speedup based on bbox
- culling. I will want to do more speedups, but none of this is
- necessary for the freeze.
-
- * art_svp_vpath.c: Fixed some bugs in the art_svp_from_vpath in
- cases where there is more than one subpath.
-
- * art_vpath.h:
- * art_vpath.c (art_vpath_perturb): Added this function. This will
- help cheat as long as the basic vector ops have numerical
- stability problems.
-
-Fri Dec 4 18:00:38 1998 Raph Levien <raph@gimp.org>
-
- * art_svp_render_aa.c (art_svp_render_aa): Changed the api
- slightly, to guarantee that the steps are all within the range
- from x0 (inclusive) to x1 (exclusive).
-
- * art_gray_svp.c, art_gray_svp.h: Added. Populated with functions
- to render into a simple graymap.
-
- * art_rgb.c, art_rgb.c: Added. Populated with fill_run and
- run_alpha methods.
-
- * art_rgb_svp.c, art_rgb_svp.h: Added. Populated with functions to
- render into an RGB buffer, and to composite over an RGB buffer.
-
- * Makefile.am: added art_gray_svp, art_rgb, and art_rgb_svp.
-
- * testart.c: test the color and layered rendering.
-
-Mon Nov 30 01:30:25 1998 Raph Levien <raph@gimp.org>
-
- * testart.c: added vector path rendering stuff. Some of it needs
- to go out of the test framework and into the module, but the
- api hasn't settled down entirely yet (in the real code, all
- x's in the step field are within bounds).
-
- * art_svp_render_aa.c, art_svp_render_aa.c.h: added.
-
- * art_svp_vpath.c, art_svp_vpath.h: added.
-
- * art_pathcode.h: added ART_MOVETO_OPEN (libart uses an
- ART_MOVETO_OPEN code at the beginning to indicate an open path,
- while PostScript uses the lack of a closepath at the end).
-
- * art_vpath_bpath.c, art_vpath_bpath.h: fixed it up, added
- flatness arg to api.
-
- * Makefile.am: added new source files.
-
-Wed Nov 25 17:19:44 1998 Raph Levien <raph@gimp.org>
-
- * art_svp.h, art_svp.c: added, basic constructors for sorted
- vector paths.
-
-Sun Nov 22 23:21:09 1998 Raph Levien <raph@gimp.org>
-

-
-Wed Nov 18 18:15:20 1998 Raph Levien <raph@gimp.org>
-
