* clutter/cogl/cogl-path.h: * clutter/cogl/common/cogl-primitives.c: * clutter/cogl/common/cogl-primitives.h: * clutter/cogl/gl/cogl-primitives.c: * clutter/cogl/gles/cogl-primitives.c: Changed the semantics of cogl_path_move_to. Previously this always started a new path but now it instead starts a new disjoint sub path. The path isn't cleared until you call either cogl_path_stroke, cogl_path_fill or cogl_path_new. There are also cogl_path_stroke_preserve and cogl_path_fill_preserve functions. * clutter/cogl/gl/cogl-context.c: * clutter/cogl/gl/cogl-context.h: * clutter/cogl/gles/cogl-context.c: * clutter/cogl/gles/cogl-context.h: Convert the path nodes array to a GArray. * clutter/cogl/gl/cogl-texture.c: * clutter/cogl/gles/cogl-texture.c: Call cogl_clip_ensure * clutter/cogl/common/cogl-clip-stack.c: * clutter/cogl/common/cogl-clip-stack.h: Simplified the clip stack code quite a bit to make it more maintainable. Previously whenever you added a new clip it would go through a separate route to immediately intersect with the current clip and when you removed it again it would immediately rebuild the entire clip. Now when you add or remove a clip it doesn't do anything immediately but just sets a dirty flag instead. * clutter/cogl/gl/cogl.c: * clutter/cogl/gles/cogl.c: Taken away the code to intersect stencil clips when there is exactly one stencil bit. It won't work with path clips and I don't know of any platform that doesn't have eight or zero stencil bits. It needs at least three bits to intersect a path with an existing clip. cogl_features_init now just decides you don't have a stencil buffer at all if you have less than three bits. * clutter/cogl/cogl.h.in: New functions and documentation. * tests/interactive/test-clip.c: Replaced with a different test that lets you add and remove clips. The three different mouse buttons add clips in different shapes. This makes it easier to test multiple levels of clipping. * tests/interactive/test-cogl-primitives.c: Use cogl_path_stroke_preserve when using the same path again. * doc/reference/cogl/cogl-sections.txt: Document the new functions.
