[B<-N>|B<--no-gridfit>]
-In order to avoid anti-aliasing effects gridlines are placed on
-integer pixel values. This is by default done by extending
-the scale so that gridlines happens to be spaced using an
-integer number of pixels and also start on an integer pixel value.
-This might extend the scale too much for some logarithmic scales
-and for linear scales where B<--alt-autoscale> is needed.
-Using B<--no-gridfit> disables modification of the scale.
+In order to avoid anti-aliasing blurring effects rrdtool snaps
+points to device resolution pixels, this results in a crisper
+aperance. If this is not to your liking, you can use this switch
+to turn this behaviour off.
+
+Gridfitting is turned off for PDF, EPS, SVG output by default.

+[B<-R>|B<--font-render-mode> {B<normal>,B<light>,B<mono>}]
-(this gets ignored in 1.3 for now!)
+There are 3 font render modes:
+
+B<normal>: Full Hinting and Antialiasing (default)
+
+B<light>: Slight Hinting and Antialiasing
+
+B<mono>: Full Hinting and NO Antialiasing
-This lets you customize the strength of the font smoothing,
-or disable it entirely using I<mono>. By default, I<normal>
-font smoothing is used.

bitmapped, that is, without any font smoothing. By default,
no text is rendered bitmapped.
+[B<-G>|B<--graph-render-mode> {B<normal>,B<mono>}]
+
+There are 2 render modes:

[B<-E>|B<--slope-mode>]
RRDtool graphs are composed of stair case curves by default. This is in line with
