The Mesh API provides a means for submitting an extensible number of
per vertex attributes to OpenGL in a way that doesn't require format
conversions and so that the data can be mapped into the GPU (in vertex
buffer objects) for - hopefully - fast re-use.
There are a number of things we can potentially use this API for, but
right now this just provides a foundation to build on. Please read
the extensive list of TODO items in cogl-mesh.c for examples.
Please refer to the cogl-mesh section in the reference manual for
documentation of the API.

Bug 1231 - Build fails in gles flavour in revision 3442
* clutter/cogl/gles/cogl-context.h: Fix remaining use of
ClutterFixed over CoglFixed. (Michael Boccara)
* clutter/cogl/gles/cogl-fbo.c: Copy the code from gl/cogl-fbo but
use the API calls directly instead of loading an extension because
it is part of the core in GLES 2.
* clutter/cogl/gles/cogl.c (_cogl_features_init): Report
COGL_FEATURE_OFFSCREEN.
* clutter/cogl/gles/cogl-fbo.h (CoglFbo): Add gl_stencil_handle.
* clutter/cogl/gles/cogl-context.h (CoglContext): Add
viewport_store
* tests/test-fbo.c (make_shader): Conditionally use the GLES 2
names of the shader variables
* clutter/cogl/gl/cogl-texture.c (cogl_texture_polygon)
(_cogl_texture_quad_sw, _cogl_texture_quad_hw):
* clutter/cogl/gles/cogl-texture.c (cogl_texture_polygon)
(_cogl_texture_quad_sw, _cogl_texture_quad_hw): Enable backface
culling in GL if it is requested.
* clutter/cogl/gles/cogl-texture.c (_cogl_texture_quad_sw)
(_cogl_texture_quad_hw):
* clutter/cogl/gl/cogl-texture.c (_cogl_texture_quad_sw)
(_cogl_texture_quad_hw): Reorder the
vertices so that they are counter-clockwise.
* clutter/cogl/gles/cogl-context.h (CoglContext):
* clutter/cogl/gl/cogl-context.h (CoglContext): Added a flag to
store whether backface culling is currently enabled.
* clutter/cogl/gles/cogl.c (cogl_enable_backface_culling):
* clutter/cogl/gl/cogl.c (cogl_enable_backface_culling): New
function
* doc/reference/cogl/cogl-sections.txt: Add
cogl_enable_backface_culling
* 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
* clutter/cogl/gles/cogl.c:
* clutter/cogl/gl/cogl.c: The clip planes are now set using the
inverse projection matrix as the modelview matrix so that they can
be specified in screen coordinates.
* clutter/cogl/gles/cogl-context.h (CoglContext):
* clutter/cogl/gl/cogl-context.h (CoglContext): Added a member to
cache the inverse projection matrix
* clutter/clutter-fixed.h: Added a constant for converting from
radians to degrees.
* clutter/clutter-fixed.c (clutter_atani, clutter_atan2i): Added
fixed-point versions of atan and atan2.
* tests/test-clip.c: Added a test for clipping with various
rotations and depths.
* tests/Makefile.am (noinst_PROGRAMS): Added test-clip
now stored in a separate struct so they can be stored for
application program objects as well.
* clutter/cogl/gles/cogl.c: Moved stub shader functions into
separate files.
(_cogl_features_init): Report support for the shaders feature on
GLES 2
* clutter/cogl/gles/cogl-shader.h:
* clutter/cogl/gles/cogl-shader.c:
* clutter/cogl/gles/cogl-program.h:
* clutter/cogl/gles/cogl-program.c: Separate files to handle
shaders on programs on GLES. If version 1.1 is being used then the
stub functions which all fail are still used.
* clutter/cogl/gles/cogl-gles2-wrapper.c
(cogl_gles2_wrapper_init, cogl_gles2_wrapper_bind_attributes),
(cogl_gles2_wrapper_get_uniforms): Move the uniforms and attribute
bindings into a separate function so they can be used to bind on
application shaders as well.
(cogl_gles2_wrapper_update_matrix): Now takes a parameter and is
no longer static so that it can be used to update all of the
matrices when a new shader is bound.
* clutter/cogl/gles/cogl-defines.h.in: Use GL_COMPILE_STATUS for
CGL_OBJECT_COMPILE_STATUS if the latter isn't available (for
example on GLES 2).
* clutter/cogl/gles/cogl-context.h (CoglContext): Added handle
arrays for programs and shaders.
* clutter/cogl/gles/cogl-context.c (cogl_create_context)
(cogl_destroy_context): Initialize and destroy program and shader
handle array.
* clutter/cogl/gles/Makefile.am (libclutter_cogl_la_SOURCES): Add
cogl-{shader,program}.{c,h}
* 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.
cogl_blend_func caches blending setup much like cogl_enable
does with the enable flags. This separates blending factors
setup from the enable/disable operation in preparation of
the texture image retrieval fix for alpha channel on GLES.
(cogl_enable:) Does not modify blending factors anymore.
* clutter/cogl/gl(es)/cogl-context.h: CoglContext holds two
new variables to cache blending src and dst factors.
* clutter/cogl/gl(es)/cogl-context.c:
(cogl_create_context:) Initialize blending factors.
* clutter/cogl/gles/cogl-texture.c:
(cogl_texture_download_from_gl:) Set blending factors to
CGL_ONE, CGL_ZERO which fixes the slighlty improper behavior
where source colour was actually multiplied with its alpha
value in the result (not noticable on current tests).
