	* clutter/cogl/common/Makefile.am:
	* clutter/cogl/common/cogl-fixed.c: Add fixed point API, modelled

1b619c3843 Bug 1074 - FBOs on GLES
* 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.

c8b4de2d6d Bug 1196 - Texture border drawing problems
* clutter/cogl/gl/cogl-texture.c (_cogl_texture_upload_subregion_to_gl)
	(_cogl_texture_upload_to_gl):

	* clutter/cogl/gles/cogl-texture.c (_cogl_texture_upload_to_gl)
	(_cogl_texture_upload_subregion_to_gl):
	
	When uploading data to a sliced texture, fill the waste pixels
	with copies of the edge of the real texture data. Otherwise the
	value of the waste pixels are undefined so it will show artifacts
	when the texture is scaled with GL_LINEAR and the pixels are
	blended in.

ae1a4a6a30 Bug 1043 - COGL calls glTexSubImage2D() with out-of-bounds
values (SIGSEGV)

	* clutter/cogl/gl/cogl-texture.c
	(_cogl_texture_upload_subregion_to_gl): When iterating over the
	slices, discard ones that don't intersect immediatly otherwise it
	will call glTexSubImage2D with a negative width/height and then
	move the source position incorrectly. Thanks to Gwenole
	Beauchesne.

cbd77008ff * clutter/cogl/gles/cogl-gles2-wrapper.h:
* clutter/cogl/gles/cogl-gles2-wrapper.c: All of the settings and
	uniforms are now proxied into COGL variables instead of setting
	the GL uniforms directly. Just before glDrawArrays is executed a
	shader is generated using the given settings to avoid using 'if'
	statements. The shaders are cached.

	* clutter/cogl/gles/cogl-fixed-vertex-shader.glsl: 
	* clutter/cogl/gles/cogl-fixed-fragment-shader.glsl: The shaders
	are now split into parts using comments instead of 'if' statements
	so that the simplest shader can be generated on the fly.

	* clutter/cogl/gles/stringify.sh: Now splits up the shader sources
	into separate C strings where deliminated by special comments.

	* clutter/cogl/gles/cogl-program.h: 
	* clutter/cogl/gles/cogl-program.c: A custom shader can no longer
	be directly linked with the fixed-functionality replacement
	because the replacement changes depending on the settings. Instead
	the bound shader is linked with the appropriate replacement shader
	just before glDrawArrays is executed. The custom uniform variables
	must also be proxied through COGL variables because their location
	can change when relinked.

        * clutter/cogl/gl/cogl.c:
* clutter/glx/clutter-glx-texture-pixmap.c:
        Remove support for GL_TEXTURE_RECTANGLE_ARB (now using just regular
        2D textures, with optional npots extension). Simplifys code, + makes
        mipmap & shader support much more sane.

93abcf9595 cogl: define GL_READ/DRAW_FRAMEBUFFER_EXT if not available
Bug 913 - cogl fails to build on OSX

	* clutter/cogl/gl/cogl-fbo.c: define GL_READ_FRAMEBUFFER_EXT and
	GL_DRAW_FRAMEBUFFER_EXT if not defined in the build system. The
	#ifdef can fail if they're not #defines but variables or enums.
	As the values are supposed to be industry standard even then
	it shouldn't have ill effects.

e306b0135c Applied 'final patch' from bug #874
* 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

165531074b * clutter/cogl/gles/cogl-gles2-wrapper.h: The uniform numbers are
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

	* 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

	arrays for programs and shaders.

	that it can report zero clip planes.

	* clutter/cogl/gles/cogl.c:
	* clutter/cogl/gles/cogl-texture.c: Use the wrapped version of
	glGetIntegerv

	* clutter/cogl/gles/cogl-primitives.c (_cogl_path_fill_nodes): Use
	_cogl_features_available to check for the stencil buffer instead
	of an #ifdef. The stencil buffer is available in the default
	profile for the GLES 2 simulator.

    	(cogl_wrap_glDrawArrays): Store the modelview matrix in a uniform
    	as well so that it can be used for fogging calculations.

	texture image data.

	* clutter/cogl/gles/cogl-gles2-wrapper.h:
	* clutter/cogl/gles/cogl-gles2-wrapper.c: Added a wrapper for
	glTexParameteri so that it can ignore requests to set
	GL_GENERATE_MIPMAP. Added a wrapper for glGenerateMipmap that does
	nothing on GLES 1

	* 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-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.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.

	* clutter/cogl/gl/cogl-texture.c (cogl_texture_new_from_foreign):
	* clutter/cogl/gles/cogl-texture.c (cogl_texture_new_from_foreign):
	GE(*) can't be used to wrap around calls that use the return
	value.

	* clutter/cogl/gl/cogl-texture.c (_cogl_texture_quad_sw)
	(_cogl_texture_quad_hw, cogl_texture_polygon): Remove GE(*)
	wrapper around calls in the middle of a glBegin/glEnd pair which
	otherwise always generate an error because glGetError can only be
	called outside of the pair.

	* clutter/cogl/gl/cogl-internal.h: Include stdio.h when definig
	COGL_DEBUG and declare a prototype for _cogl_error_string.

	* clutter/cogl/gles/cogl-internal.h: Match GE(*) macro to GL
	version.
