e4548bcdc5 [cogl-material] Some improvements for how we sync CoglMaterial state with OpenGL
This flattens the three functions: cogl_material_flush_gl_material_state,
.._flush_gl_alpha_func and .._flush_gl_blend_func into one:
cogl_flush_material_gl_state which doesn't takes a material handle. (the handle
is instead taken from the context.)

This has allows us to avoid re-submitting some state to OpenGL when the
material has not been replaced.

Note: Avoiding redundant state changes for material layers isn't dealt with
in this patch.

61b8cc1874 Adds a CoglMaterial abstraction, which includes support for multi-texturing
My previous work to provide muti-texturing support has been extended into
a CoglMaterial abstraction that adds control over the texture combine
functions (controlling how multiple texture layers are blended together),
the gl blend function (used for blending the final primitive with the
framebuffer), the alpha function (used to discard fragments based on
their alpha channel), describing attributes such as a diffuse, ambient and
specular color (for use with the standard OpenGL lighting model), and
per layer rotations. (utilizing the new CoglMatrix utility API)

For now the only way this abstraction is exposed is via a new
cogl_material_rectangle function, that is similar to cogl_texture_rectangle
but doesn't take a texture handle (the source material is pulled from
the context), and the array of texture coordinates is extended to be able
to supply coordinates for each layer.

Note: this function doesn't support sliced textures; supporting sliced
textures is a non trivial problem, considering the ability to rotate layers.
Note: cogl_material_rectangle, has quite a few workarounds, for a number of
other limitations within Cogl a.t.m.
Note: The GLES1/2 multi-texturing support has yet to be updated to use
the material abstraction.

509928cc76 [multi-texturing] This adds a new cogl_multi_texture API for GL,GLES1 + GLES2
Multitexturing allows blending multiple layers of texture data when texturing
some geometry. A common use is for pre-baked light maps which can give nice
lighting effects relativly cheaply. Another is for dot-3 bump mapping, and
another is applying alpha channel masks.

The dot-3 bump mapping would be really nice one day, but currently cogl doesn't
support lighting so that's not dealt with in this patch.

notable limitations:
- It can only texture rectangles a.t.m - and like cogl_texture_rectangle there
is no support for rotated texturing.
- Sliced textures are not supported. I think I've figured out how to handle
layers with different slice sizes at least for rectangular geometry, but I'm
not sure how complex it becomes once rotations are possible and texturing
arbitrary cogl_polygons.
- Except for this new API, cogl still doesn't know about more than one texture
unit, and so has no way of caching any enables related to other units. So that
things don't break it's currently necessary to disable anything to do with
additional units as soon as we are done with them which isn't ideal.
- No clutter API yet.

b11b74fcde Use a single index array
There's no point in clearing the index array because it is always the
same sequence of indices regardless of the vertices. Instead it is
just added to when there are more vertices than ever before.

7a276affd6 Use the correct length in _cogl_texture_flush_vertices
The check for whether there are any rectangles to flush was using the
wrong value so it would always flush.

	* clutter/cogl/gles/cogl-primitives.c: Changed the semantics of

	now it instead starts a new disjoint sub path. The path isn't

	* 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.

be655b05ad Bug 1305 - NPOT textures unaligned to a pixel sometimes have
border artifacts

	* clutter/cogl/gl/cogl-texture.c: Set the wrap mode of a texture
	on demand

	Instead of setting the wrap mode once per texture at creation, it
	is now changed whenever the texture is drawn. The previous value
	is cached so that it isn't changed if the value is the same.

	This is used in _cogl_texture_quad_hw to only enable GL_REPEAT
	mode when the coordinates are not in the range [0,1]. Otherwise it
	can pull in pixels from the other edge when the texture is
	rendered off-pixel.

flushes the vertices after calling either of the functions.

* 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)

	When uploading data to a sliced texture, fill the waste pixels

	value of the waste pixels are undefined so it will show artifacts
	when the texture is scaled with GL_LINEAR and the pixels are

	* clutter/cogl/gl/cogl-texture.c (cogl_texture_new_from_foreign):

(cogl_texture_download_from_gl:) Store old blending factors
	and restore them when done. The lack of ability to retrieve
	the alpha channel now more noticable in test-cogl-tex-getset
	since the edges of the hand are not antialiased.

	* clutter/cogl/gl(es)/cogl-internal.h: Declare

	warning.

d049d9ead4 * 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).

        * 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.

	OpenGL header location, so it basically did break every application
	including clutter/cogl.h because the GL header inclusion depended
	on symbols defined into Clutter's config.h. Now, we define the
	GL header into the configure template and use it to create the
	cogl-defines.h file cogl.h includes.

        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.

        * clutter/clutter-stage.c: (clutter_stage_get_actor_at_pos):
        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/cogl.h:

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

        * configure.ac:
        Add initial 'cogl' implementation. 'cogl' is a simple abstration
        layer over GL and GL/ES used by clutter internally. It should
        eventually allow clutter applications to be run on both GL and GL/ES
        with just a recompile as well as provide more debugging and potentially
        profiling information for GL and GL/ES usage.

        This commit contains the initial GL implementation.
