Bug 1172 - Disjoint paths and clip to path * 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.

2008-10-30 Emmanuele Bassi <ebassi@linux.intel.com> Bug 1209 - Move fixed point API in COGL * clutter/cogl/cogl-fixed.h: * clutter/cogl/cogl.h.in: * clutter/cogl/common/Makefile.am: * clutter/cogl/common/cogl-fixed.c: Add fixed point API, modelled after the ClutterFixed. The CoglFixed API supercedes the ClutterFixed one and avoids the dependency of COGL on Clutter's own API. * clutter/cogl/common/cogl-clip-stack.c: * clutter/cogl/common/cogl-primitives.c: * clutter/cogl/common/cogl-primitives.h: Update internal usage of ClutterFixed to CoglFixed. * clutter/cogl/gl/Makefile.am: * clutter/cogl/gl/cogl-primitives.c: * clutter/cogl/gl/cogl-texture.c: * clutter/cogl/gl/cogl.c: Ditto, in the GL implementation of the COGL API. * clutter/cogl/gles/Makefile.am: * clutter/cogl/gles/cogl-fbo.c: * clutter/cogl/gles/cogl-gles2-wrapper.c: * clutter/cogl/gles/cogl-primitives.c: * clutter/cogl/gles/cogl-texture.c: * clutter/cogl/gles/cogl.c: Ditto, in the GLES implementation of the COGL API. * clutter/pango/pangoclutter-glyph-cache.c: * clutter/pango/pangoclutter-glyph-cache.h: Ditto, in the Pango renderer glyphs cache. * clutter/clutter-fixed.c: * clutter/clutter-fixed.h: ClutterFixed and related API becomes a simple transition API for bindings and public Clutter API. * clutter/clutter-actor.c: * clutter/clutter-alpha.c: * clutter/clutter-backend.c: * clutter/clutter-behaviour-depth.c: * clutter/clutter-behaviour-ellipse.c: * clutter/clutter-behaviour-path.c: * clutter/clutter-behaviour-rotate.c: * clutter/clutter-behaviour-scale.c: * clutter/clutter-clone-texture.c: * clutter/clutter-color.c: * clutter/clutter-entry.c: * clutter/clutter-stage.c: * clutter/clutter-texture.c: * clutter/clutter-timeline.c: * clutter/clutter-units.h: Move from the internal usage of ClutterFixed to CoglFixed. * doc/reference/clutter/clutter-sections.txt: * doc/reference/cogl/cogl-docs.sgml: * doc/reference/cogl/cogl-sections.txt: Update the documentation. * tests/test-cogl-tex-tile.c: * tests/test-project.c: Fix tests after the API change * README: Add release notes.
