* 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
