In gimp_display_shell_expose_region(), invalidate each rect rather
than rebuilding the cairo_region_t as GdkRegion and then invalidating
the entire GdkRegion. Improves performance for tools that invalidate
complex regions.
This removes the obsolete check which makes the tool fail from
gimp_display_shell_set_mask(). Also change the foreground select tool
and the display mask from using GimpChannel to GeglBuffer, because
that's what it needs, simply buffers. Most changed files simply newly
include <gegl.h> because a GeglBuffer appeared in two headers.
and completely separate configure and sanity checks for gdk-pixbuf
from GTK+, because it's now distributed as a separate package. Remove
all sorts of conditional compiling based on GDK_CHECK_VERSION() and
CAIRO_VERSION.
This is a gross hack that typedefs around between GdkRegion and
cairo_region_t and has some evil #ifdefs. This is going to die
immeditately once we can depend on cairo 1.10.
which gets emitted when the item wants to be redrawn:
- Emit "update" it when any item property changes
- Groups connect to their children and forward "update" for them
- The shell connects to its group of canvas items and exposed
the affected area
- Remove gimp_display_shell_expose_item()
- Move all the shell's item group code into gimpdisplayshell-items.c
