* clutter/cogl/gl/cogl.c:
* clutter/cogl/gles/cogl.c:
* clutter/cogl/cogl.h.in: Add cogl_clip_stack_save,
cogl_clip_stack_restore, cogl_viewport and cogl_frustum.
* clutter/cogl/gl/cogl-fbo.h:
* clutter/cogl/gl/cogl-fbo.c: Try to attach a stencil buffer when
creating an FBO.
* clutter/cogl/common/cogl-clip-stack.c: Add functions to save and
restore the whole state of the stack.
* clutter/clutter-texture.c (clutter_texture_paint): When
rendering the FBO source, setup a temporary asymmetric perspective
projection matrix to render it as it would appear on screen.
* clutter/clutter-private.h:
* clutter/clutter-actor.c
(_clutter_actor_apply_modelview_transform_recursive): No longer
static and exported in clutter-private.h
* clutter/cogl/common/cogl-clip-stack.h:
* clutter/cogl/common/cogl-clip-stack.c: Added functions to
maintain a stack of clipping rectangles.
* clutter/cogl/gles/cogl.c:
* clutter/cogl/gl/cogl.c: The cogl_clip_set and unset functions
have moved into cogl-clip-stack.c which calls back to cogl.c to
set the actual rectangles. Multiple clip rectangles are combined
by merging the stencil buffers.
* clutter/cogl/gles/cogl-primitives.c (_cogl_path_fill_nodes):
* clutter/cogl/gl/cogl-primitives.c (_cogl_path_fill_nodes): Merge
the stencil buffer with the contents of the clipping stack after
drawing the path.
* clutter/cogl/gles/cogl-context.h (CoglContext):
* clutter/cogl/gl/cogl-context.h (CoglContext): Store the number
of available stencil bits.
* clutter/cogl/common/Makefile.am
(libclutter_cogl_common_la_SOURCES): Added cogl-clip-stack.c
