+To avoid antialiasing effects gridlines are placed on

+the scale so gridlines happends to be spaced using an 
+integer number of pixels, and starts on integer pixel value.
+This might extend the scale too much for some logarithmic scales

+Using --no-gridfit disables modification of the scale,
+and just truncates y-coordinates to integer values for bitmap
+formats.
