This is the GdkRgb integration.
* app/gximage.c (gximage_put): Uses gdk_draw_rgb_image rather
than gdk_draw_image.
* app/image_render.c: gutted most of this, as it is now subsumed
by GdkRgb. In the process, gamma != 1.0 doesn't work anymore.
Also, speedups are almost certainly possible in a bunch of cases.
* app/info_window.c (get_shades): compiles and runs, but is
not functional.
* app/colormaps.c: gutted
* app/color_select.c: changed dither to max
A few things remain: the dithering is _not_ correctly aligned for
scrolling - looks like I'll need to add some more API to GdkRgb
for that. The gradient editor needs to be set to maximum
dithering. I'd like to draw the foreground and background colors
dithered so they don't quantize so much in 8bpp modes.
