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.

GLES 2 backend * clutter/eglx/clutter-stage-egl.h: * clutter/eglx/clutter-egl-headers.h: * clutter/eglx/clutter-backend-egl.h: * clutter/eglx/Makefile.am: Include the GLES and EGL headers via clutter-egl-headers.h so that the right version can be used depending on whether the GLES 2 wrapper is being used. * configure.ac: Added an automake conditional for whether the GLES 2 wrapper should be used. * clutter/eglx/clutter-stage-egl.c (clutter_stage_egl_realize): Remove the call to glGetIntegerv to get the max texture size. It was being called before the GL context was bound so it didn't work anyway and it was causing trouble for the GLES 2 simulator. * clutter/cogl/gles/stringify.sh: Shell script to convert the shaders into a C string. * clutter/cogl/gles/cogl-gles2-wrapper.h: * clutter/cogl/gles/cogl-gles2-wrapper.c: Wrappers for most of the missing GL functions in GLES 2. * clutter/cogl/gles/cogl-fixed-fragment-shader.glsl: * clutter/cogl/gles/cogl-fixed-vertex-shader.glsl: New shaders for GLES 2 * clutter/cogl/gles/cogl-defines.h.in: Use the @CLUTTER_GL_HEADER@ macro instead of always using the GLES 1 header. * clutter/cogl/gles/cogl-context.h (CoglContext): Include a field for the state of the GLES 2 wrapper. * clutter/cogl/gles/cogl-texture.c: * clutter/cogl/gles/cogl-primitives.c: * clutter/cogl/gles/cogl.c: Use wrapped versions of the GL functions where neccessary. * clutter/cogl/gles/Makefile.am: Add sources for the GLES 2 wrapper and an extra build step to put the GLSL files into a C string whenever the files change.
