2001-01-11 Alexander Larsson <alexl@redhat.com> * acconfig.h: Added ENABLE_SHADOW_FB * configure.in: Added --disable-shadowfb * gdk/linux-fb/gdkcursor-fb.c: Update shadowfb when updating cursor * gdk/linux-fb/gdkdrawable-fb2.c: Added wrappers for shadowfb that calls the normal drawable methods, but calls gdk_shadow_fb_update(bounding box) when GdkWindows are drawed to. Moved gdk_draw_glyphs implementation to _gdk_draw_glyphs which also returns the bounding box. * gdk/linux-fb/gdkfb.h: Added GdkFBAngle type and gdk_fb_set_rotation declaration. * gdk/linux-fb/gdkgeometry-fb.c: Update shadowfb when scrolling window. * gdk/linux-fb/gdkglobals-fb.c: Add _gdk_fb_screen_angle. * gdk/linux-fb/gdkkeyboard-fb.c: Test code for screen rotation. Shift-F2 in the xlate driver rotates the screen. * gdk/linux-fb/gdkmain-fb.c: Handle shadowfb. Add gdk_fb_set_rotation(). Remove CM and RP. * gdk/linux-fb/gdkmouse-fb.c: Use fb_width/height instead of modeinfo.xres/yres. * gdk/linux-fb/gdkprivate-fb.h: Added fb_men, fb_width, fb_height & fb_stride. When using shadow fb these can differ from the framebuffer stuff. Declarations for gdk_shadow_fb_update, gdk_shadow_fb_init, gdk_shadow_fb_stop_updates, gdk_fb_recompute_all, _gdk_fb_screen_angle. Removed CM, RP. * gdk/linux-fb/gdkrender-fb.c: Added code for shadowfb handling and screen rotation using shadowfb. * gdk/linux-fb/gdkwindow-fb.c: Use fb_mem, fb_stride, fb_width, fb_height. Added recompute_rowstride to reset the rowstride of all windows. Added gdk_fb_recompute_all() which recomputes rootwindow size, window abs positions and window rowstrides. Usefull when the rotation has changed.
