* gdk/x11/gdkdrawable-x11.c gdk/x11/gdkprivate-x11.h
(_gdk_x11_have_render): Private function to tell if we have RENDER
extension.
* gdk/x11/gdkgc-x11.c (_gdk_x11_gc_get_fg_picture): Return
None if we don't have RENDER extension.
* gdk/x11/gdkpango-x11.c (gdk_pango_context_get): Don't
use Xft unless we have render extension.
* gdk/x11/gdkdrawable-x11.c (gdk_x11_drawable_get_picture):
Handle missing render extension.
* gdk/gdkdraw.c gdk/gdkdrawable.h gdk/gdkpixmap.c gdk/gdkwindow.c
gdk/gdkinternals.h: Add a private copy_to_image() virtual function
to the GdkDrawable vtable that extends get_image() to allow
copying onto existing images. Make the default implementation of
get_image() use this so that backends don't have to implement
both. Add private wrapper _gdk_drawable_copy_to_image().
* gdk/x11/gdkimage-x11.c gdk/x11/gdkprivate-x11.c
gdk/x11/gdkdrawable-x11.c (_gdk_x11_copy_to_image): Implement
copy_to_image() semantics, speed up by using ShmPixmaps and
XCopyArea when possible, XFlush() after ungrabbing the server,
generally redo the logic once again.
* gdk/gdkinternals.h gdk/x11/gdkimage-x11.c
_gdk_windowing_bits_per_depth(): Function to convert from depth to
bits-per-pixel. (We assume only one bpp per depth - X requires
this.)
* gdk/gdkinternals.h gdk/gdkrgb.c gdk/gdkimage.c: Move the GdkRGB
scratch image code into a generic _gdk_image_get_scratch() chunk
of code that we can use other places we need scratch images.
* gdk/gdkimage.c gdk/x11/gdkimage.c gdk/gdkinternals.h:
Add _gdk_image_new_for_depth() as the backend
to _gdk_image_new() to allowing creating images with
a depth and no visual.
* gdk/gdkpixbuf-drawable.c: Fix so that getting
parts of images not at 0,0 actually works.
* gdk/gdkdrawable.h gdk/gdkinternals.h gdk/gdkdraw.c
gdk/gdkwindow.c gdk/gdkpixmap.c gdk/gdkpixbuf-render.c:
- Add a new GdkDrawableClass vfunc _draw_pixbuf, and
_gdk_draw_pixbuf() [ will be made public later ], to allow
backends to accelerate drawing pixbufs.
- Move the implementation of gdk_pixbuf_render_to_drawable_alpha()
to be the default implementation.
- Update docs for gdk_pixbuf_render_to_drawable_alpha().
- Optimize the default implementation by using
_gdk_image_copy_to_pixmap() and scratch shared images, and
special casing the compositing.
* gdk/x11/gdkdrawable-x11.c: Accelerate _gdk_draw_pixbuf()
with alpha using the RENDER extension.
* gdk/gdkpixbuf-drawable.c (gdk_pixbuf_get_from_drawable):
Optimize by _gdk_image_copy_to_pixmap() and scratch images.
* tests/testrgb.c: Add test for speed of alpha composition,
reduce the number of iterations since alpha composition
can be a bit slow.
* gdk/x11/gdkimage-x11.c gdk/gdkprivate-x11.h (_gdk_x11_image_get_shm_pixmap):
Private function to get a ShmPixmap for an image, if possible.
