Refactored the GimpDisplayShell update/draw code:
* app/display/gimpdisplayshell.[ch]: removed the display_areas
list which used to hold the GimpAreas to update. Instead, simply
queue draws using gtk_widget_queue_draw[_area]() in
gimp_display_shell_expose_area(), _expose_full() and
_expose_guide(). Made all _draw() functions public because they
are now called from the "expose_event" handler. Removed rendering
from gimp_display_shell_flush() because stuff is now flushed
automatically by the gtk idle renderer.
* app/display/gimpdisplayshell-callbacks.c
(gimp_display_shell_canvas_expose): draw everything here (the code
removed from gimp_display_shell_flush() without the GimpArea list).
(gimp_display_shell_canvas_tool_events): return "return_val", not
TRUE if gimp->busy is TRUE. Fixes unupdated (windowk bg color)
display areas. Fixes bug #106595.
* app/display/gimpdisplay.c
* app/display/gimpdisplayshell-cursor.c
* app/display/gimpdisplayshell-filter-dialog.c
* app/display/gimpdisplayshell-handlers.c
* app/display/gimpdisplayshell-selection.c
* app/gui/view-commands.c: changed accordingly. Removed calls to
gimp_display_shell_flush() all over the place.
* app/display/gimpdisplayshell-scroll.c: replaced lots of code by
a single call to gdk_window_scroll().
