2005-05-09 Owen Taylor <otaylor@redhat.com> * gdk/gdkrgb.c (gdk_rgb_convert_0888_br, gdk_rgb_convert_8880_br): Fill in unused bits so they can be used for the depth-32 target case. Rewrite so that that gives a marginal speedup rather than a marginal slowdown. (on x86) * gdk/gdkscreen.h gdk/x11/gdkscreen-x11.[ch] gdk/x11/gdkvisual-x11.c: Add gdk_screen_get_rgba_colormap/visual to get a visual for windows with an alpha channel, if one exists. * gdk/win32/gdkscreen-win32.c gdk/linux-fb/gdkscreen-fb.c: Stub out gdk_screen_get_rgba_colormap/visual. * gdk/x11/gdkcolor-x11.c (gdk_colormap_alloc_colors): computation of "unused" wasn't right for depth == 32, since it depended on shifting by 32. * gdk/gdkrgb.c: Fill in alpha bits with 1s. (Based on patch from Keith Packard, http://mail.gnome.org/archives/gtk-devel-list/2004-June/msg00080.html) * gdk/x11/gdkdrawable-x11.c (gdk_x11_drawable_get_picture): Implement again, without using Xft. * tests/testgtk.c: Add a test for windows with an alpha channel.
