Sun Jul 2 12:45:50 2000 Owen Taylor <otaylor@redhat.com> * gdk/gdkrgb.[ch]: Add gdk_rgb_find_color() to get a pixel value using GdkRGB functionality given GdkColormap and GdkColor. (name not final, waiting for inspiration.) * gdk/gdkgc.[ch] (gdk_gc_set_rgb_fg/bg_color): New functions to set the foreground/background of a GC using the GC's colormap and GdkRGB. (name not final, waiting for inspiration.) * gdk/gdkcompat.h gdk/gdkrgb.c (gdk_rgb_get_colormap): Rename from gdk_rgb_get_cmap(), put #define in gdkcompat.h. * gtk/gtkwidget.[ch] gtkcompat.h: Make visuals for gtk_widget_get_visual(), gtk_widget_get_default_visual, etc, purely a function of the corresponding colormap. Make gtk_widget_set_visual(), etc, noop macros in gtkcompat.h. * gdk/gdkpixmap.c gdk/x11/gdkpixmap-c11.c: Rewrite gdk_pixbuf_*create_from_xpm_* in terms of gdk_pixbuf_new_from_xpm_data(), move into platform independent code. * gdk/gdkpixbuf-render.c (gdk_pixbuf_render_to_drawable): Take advantage of the new draw_rgb_32_image_dithalign. * gdk/gdkrgb.c (gdk_draw_rgb_32_image_dithalign): Added. * gtk/gtkgc.c (gtk_gc_new): Set the appropriate colormap on each created GC. * gdk/gdkgc.[ch]: Add gdk_gc_get/set_colormap. * gdk/gdkgc.[ch]: Add a colormap field to the GdkGC structure which we initialize from the drawable when the GC is created, if the drawable has a colormap. * gdk/x11/gdkgc-x11.c: include string.h for memset. * gdk/x11/gdkinput-x11.c: include string.h for strlen, etc. * gtk/gtklayout.[ch]: Remove unsed configure serial member.
