* gdk/gdktypes.h: Add new type GdkSpan * docs/reference/gdk/gdk-sections.txt, docs/reference/gdk/tmpl/regions.sgml, gdk/gdkregion-generic.c, gdk/gdkregion.h: Implement and document gdk_region_spans_intersect_foreach. * gdk/linux-fb/Makefile.am, gdk/linux-fb/gdkrender-fb.c: Add new file gdkrender-fb.c which contains all core rendering code. Add gdk_fb_fill_rectangle_generic (old rectangle code) and gdk_fb_fill_rectangle_simple_16, gdk_fb_fill_rectangle_simple_32 (optimized rectangle fillers). * gdk/linux-fb/gdkdrawable-fb2.c: Move all rendering code to gdkrender-fb.c. Change from using GdkRectangles and GdkSegments for spans to GdkSpan. Use the new span intersection functions in gdk_fb_fill_spans. gdk_fb_draw_rectangle() clips filled rectangles and calls gc->fill_rectangle with the result. gdk_fb_fill_spans() gets extra argument "sorted". * gdk/linux-fb/gdkevents-fb.c: Remove unused includes and defines. New function gdk_fb_get_time() to get correct time for events. * gdk/linux-fb/gdkinput-ps2.c: Use gdk method of generating multiple-clicks (gdk_event_button_generate) Make sure to set the time of all events. * gdk/linux-fb/gdkmain-fb.c: Use gdk_fb_get_time (). * gdk/linux-fb/gdkprivate-fb.h: New virtual GC calls: fill_span & fill_rectangle. Export gdk_fb_get_time(). gdk_fb_fill_spans() gets extra argument "sorted". * gdk/linux-fb/mi*.c: Use GdkSpan instead of GdkRectangle. Pass correct sorted to gdk_fb_fill_spans.
