a2cf7e4a19 [Automatic fixed-to-float.sh change] Applies a number fixed to float patches
To deal with all the corner cases that couldn't be scripted a number of patches
were written for the remaining 10% of the effort.

Note: again no API changes were made in Clutter, only in Cogl.

e82f656590 [Automatic fixed-to-float.sh change] Applies all scripted changes
This is the result of running a number of sed and perl scripts over the code to
do 90% of the work in converting from 16.16 fixed to single precision floating
point.

Note: A pristine cogl-fixed.c has been maintained as a standalone utility API
      so that applications may still take advantage of fixed point if they
      desire for certain optimisations where lower precision may be acceptable.

Note: no API changes were made in Clutter, only in Cogl.

Overview of changes:
- Within clutter/* all usage of the COGL_FIXED_ macros have been changed to use
the CLUTTER_FIXED_ macros.

- Within cogl/* all usage of the COGL_FIXED_ macros have been completly stripped
and expanded into code that works with single precision floats instead.

- Uses of cogl_fixed_* have been replaced with single precision math.h
alternatives.

- Uses of COGL_ANGLE_* and cogl_angle_* have been replaced so we use a float for
angles and math.h replacements.

89e7552ca3 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.

* clutter/cogl/cogl-color.h:
	* clutter/cogl/cogl-path.h:
	* clutter/cogl/cogl-types.h:
	* clutter/cogl/common/cogl-color.c: Deprecated cogl_color()
	in favour of cogl_set_source_color() and friends; store the
	CoglColor components as unsigned bytes instead of fixed point
	normalized values; add functions for allocating, copying and
	freeing CoglColor, for use of language bindings.

	* clutter/cogl/cogl.h.in:

* clutter/cogl/common/cogl-fixed.c (cogl_fixed_sin)
	(cogl_angle_sin, cogl_angle_tan, cogl_fixed_sqrt): Replaced uses

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

04ce490c0a 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.

dff84094ff Bug 918 - Group doesn't clip if it's children are clipped
* 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

8bdb98736d 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.

	* 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.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

	testing.

	* clutter/cogl/gles/cogl-gles2-wrapper.h:
	* clutter/cogl/gles/cogl-gles2-wrapper.c
	(cogl_wrap_glGetIntegerv): Added a wrapper for glGetIntegerv so
	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

	* 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-primitives.c:
	* clutter/cogl/gles/cogl.c: Use wrapped versions of the GL
	functions where neccessary.

f9e43c440b * clutter/cogl/gl/cogl.c (error_string):
* clutter/cogl/gles/cogl.c (error_string): Rename to
	_cogl_error_string and remove the static scoping so that it can be
	called in cogl-texture etc.

	* 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.

f2d701c809 * clutter/cogl/gl(es)/cogl.c: New internal function
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).

19058afe82 Removed COGLhandle and changed shader and program functions to be
wrapped in reference-counted CoglHandles instead.

	* clutter/cogl/gl/cogl-shader.c: 
	* clutter/cogl/gl/cogl-shader.h: 
	* clutter/cogl/gl/cogl-program.c: 
	* clutter/cogl/gl/cogl-program.h: 
	New files to hold the shader and program functions.

	* clutter/cogl/gl/cogl.c: Removed shader and program functions.

	* clutter/cogl/common/cogl-handle.h: New header to define
	COGL_HANDLE_DEFINE which helps build functions to create
	reference-counted handles. This reduces the amount of duplicated
	code.

	* clutter/cogl/gl/cogl-texture.c: 
	* clutter/cogl/gles/cogl-texture.c: 
	* clutter/cogl/gl/cogl-fbo.c: Converted to use COGL_HANDLE_DEFINE
	from cogl-handle.h to avoid duplicating some of the common code.

	* clutter/cogl/gles/cogl-defines.h.in: 
	* clutter/cogl/gl/cogl-defines.h.in: Removed COGLhandle

	* clutter/cogl/gl/cogl-context.h: Added handle arrays for programs
	and shaders.

	* clutter/cogl/gl/cogl-context.c (cogl_create_context): Added
	initialisers for shader_handles and program_handles.
	(cogl_destroy_context): Added calls to g_array_free for all handle
	arrays.

	* clutter/cogl/gl/Makefile.am (libclutter_cogl_la_SOURCES): Added
	cogl-{program,shader}.{c,h}

	* clutter/cogl/common/Makefile.am
	(libclutter_cogl_common_la_SOURCES): Added cogl-handle.h

	* clutter/cogl/gles/cogl.c:
	* clutter/cogl/cogl.h.in: Programs and shaders are now wrapped in
	CoglHandles instead of COGLhandles. cogl_program_destroy and
	cogl_shader_destroy is now replaced with cogl_program_unref and
	cogl_shader_unref. cogl_program_ref and cogl_shader_ref are also
	added.

	* clutter/clutter-shader.c: Converted to use CoglHandles for the
	programs and shaders instead of COGLhandles.

	* cogl/cogl-sections.txt: Added cogl_shader_ref,
	cogl_shader_unref, cogl_is_shader, cogl_program_ref,
	cogl_program_unref, cogl_is_program and cogl_is_offscreen.

* clutter/cogl/cogl.h:
        * clutter/cogl/gl/cogl.c:
        * clutter/cogl/gles/cogl.c:
       Disable the depth test and buffer as has some strange side
       effects, mainly on x/y axis rotation with multiple layers at
       same depth (eg rotating text on a bg has very strange
       effect). Seems no clean 100% effective way to fix without other
       odd issues.. So for now move to application to handle and add
       cogl_enable_depth_test() as for custom actors (i.e groups) to
       enable if need be.

        Add initial experiemental YUV texture support.
        Move texture rect size checks into cogl.
        Better handle moving texture data from video -> system memory
        (if support available).

        * clutter/glx/clutter-stage-glx.c:
        * clutter/glx/clutter-backend-glx.c:
        Fix up rendering pipeline removing clutter_backend_XXX_stage_paint
        and adding clutter_backend_XXX_redraw instead. Duplicates less
        code in backends, avoids clutter_actor_paint() getting called
        before stage is set up (viewport wise) and unbreaks things like
        picking.

        Redo picking functionality a different way (via color indexing)
        as to provide more flexibility, possibly speed and more likely
        work with GL/ES (doesn't currently however - not sure why).

        * clutter/clutter-group.c:
        Add groups own 'pick' method.

        * clutter/cogl/gles/cogl-defines.h:
        Hack around missing BGR format in GL/ES.
