>(it currently calls itself drawing routines which is NOT a good idea
I'll reply to the rest of these statements/comments in a bit, but this one
above is just horribly wrong.
class GR_UnixGnomeImage : public GR_RasterImage
There are a few #ifdefs in GR_UnixGraphics to specifically handle GdkPixbuf
vs. PNG images. As it currently stands, the GR_Graphics class *must* know
about UnixImage vs. UnixGnomeImage, because the createImage() and
drawImage() routines lie there... We're not advanced to the point where we
can say something like the following:
GR_Image * foo = new GR_Image(filename);
In this case, everything could be done entirely XP. But now, we depend on
being able to basically extract RGB(A) buffers from images and paste them
onto drawables in *every* graphics impl, not just Unix. Until we go entirely
XP here (which I doubt that we'll ever do), Graphics _must_ know about
Image's implementation, which is perfectly fine here because *Graphics' role
is a creator/manager/renderer of a specific subclass of GR_Image.
This code is not broken.
