Fully integrates CoglMaterial throughout the rest of Cogl

Browse Source 
This glues CoglMaterial in as the fundamental way that Cogl describes how to
fill in geometry.

It adds cogl_set_source (), which is used to set the material which will be
used by all subsequent drawing functions

It adds cogl_set_source_texture as a convenience for setting up a default
material with a single texture layer, and cogl_set_source_color is now also
a convenience for setting up a material with a solid fill.

"drawing functions" include, cogl_rectangle, cogl_texture_rectangle,
cogl_texture_multiple_rectangles, cogl_texture_polygon (though the
cogl_texture_* funcs have been renamed; see below for details),
cogl_path_fill/stroke and cogl_vertex_buffer_draw*.

cogl_texture_rectangle, cogl_texture_multiple_rectangles and
cogl_texture_polygon no longer take a texture handle; instead the current
source material is referenced. The functions have also been renamed to:
cogl_rectangle_with_texture_coords, cogl_rectangles_with_texture_coords
and cogl_polygon respectivly.

Most code that previously did:
  cogl_texture_rectangle (tex_handle, x, y,...);
needs to be changed to now do:
  cogl_set_source_texture (tex_handle);
  cogl_rectangle_with_texture_coords (x, y,....);

In the less likely case where you were blending your source texture with a color
like:
  cogl_set_source_color4ub (r,g,b,a); /* where r,g,b,a isn't just white */
  cogl_texture_rectangle (tex_handle, x, y,...);
you will need your own material to do that:
  mat = cogl_material_new ();
  cogl_material_set_color4ub (r,g,b,a);
  cogl_material_set_layer (mat, 0, tex_handle));
  cogl_set_source_material (mat);

Code that uses the texture coordinates, 0, 0, 1, 1 don't need to use
cog_rectangle_with_texure_coords since these are the coordinates that
cogl_rectangle will use.

For cogl_texture_polygon; as well as dropping the texture handle, the
n_vertices and vertices arguments were transposed for consistency. So
code previously written as:
  cogl_texture_polygon (tex_handle, 3, verts, TRUE);
need to be written as:
  cogl_set_source_texture (tex_handle);
  cogl_polygon (verts, 3, TRUE);

All of the unit tests have been updated to now use the material API and
test-cogl-material has been renamed to test-cogl-multitexture since any
textured quad is now technically a test of CoglMaterial but this test
specifically creates a material with multiple texture layers.

Note: The GLES backend has not been updated yet; that will be done in a
following commit.

Cogl API changes for Clutter 1.0
--------------------------------
* All drawing functions now use a source material to determine how geometry is
filled. The source material is set via cogl_set_source. Or the convenience
functions cogl_set_source_color and cogl_set_source_texture.
"drawing functions" include: cogl_rectangle, cogl_texture_rectangle,
cogl_texture_multiple_rectangles, cogl_texture_polygon (though the
cogl_texture_* funcs have been renamed; see below for details),
cogl_path_fill/stroke and cogl_vertex_buffer_draw*.
cogl_texture_rectangle, cogl_texture_multiple_rectangles and
cogl_texture_polygon no longer take a texture handle; instead the current
source material is referenced. The functions have also been renamed to:
cogl_rectangle_with_texture_coords, cogl_rectangles_with_texture_coords
and cogl_polygon respectively.
Most code that previously did:
cogl_texture_rectangle (tex_handle, x, y,...);
needs to be changed to now do:
cogl_set_source_texture (tex_handle);
cogl_rectangle_with_texture_coords (x, y,....);
In the less likely case where you were blending your source texture with a
color like:
cogl_set_source_color4ub (r,g,b,a); /* (where r,g,b,a isn't just white) */
cogl_texture_rectangle (tex_handle, x, y,...);
you will need your own material to do that:
material = cogl_material_new ();
cogl_material_set_color4ub (r,g,b,a);
cogl_material_set_layer (material, 0, tex_handle));
cogl_set_source_material (material);
Code that uses the texture coordinates, 0, 0, 1, 1 don't need to use
cogl_rectangle_with_texure_coords since these are the coordinates that
cogl_rectangle will use.
For cogl_texture_polygon; as well as dropping the texture handle, the
n_vertices and vertices arguments were transposed for consistency. So
code previously written as:
cogl_texture_polygon (tex_handle, 3, verts, TRUE);
need to be written as:
cogl_set_source_texture (tex_handle);
cogl_polygon (verts, 3, TRUE);
* A CoglMesh type and utility API has been added; this is currently used to
support describing texture matrices.

/**
* _cogl_material_flush_layers_gl_state:
* @fallback_mask: is a bitmask of the material layers that need to be
* replaced with the default, fallback textures. The fallback textures are
* fully transparent textures so they hopefully wont contribute to the
* texture combining.
*
* The intention of fallbacks is to try and preserve
* the number of layers the user is expecting so that texture coordinates
* they gave will mostly still correspond to the textures they intended, and
* have a fighting chance of looking close to their originally intended
* result.
*
* @disable_mask: is a bitmask of the material layers that will simply have
* texturing disabled. It's only really intended for disabling all layers
* > X; i.e. we'd expect to see a contiguous run of 0 starting from the LSB
* and at some point the remaining bits flip to 1. It might work to disable
* arbitrary layers; though I'm not sure a.t.m how OpenGL would take to
* that.
*
* The intention of the disable_mask is for emitting geometry when the user
* hasn't supplied enough texture coordinates for all the layers and it's
* not possible to auto generate default texture coordinates for those
* layers.
*
* @layer0_override_texture: forcibly tells us to bind this GL texture name for
* layer 0 instead of plucking the gl_texture from the CoglTexture of layer
* 0.
*
* The intention of this is for any geometry that supports sliced textures.
* The code will can iterate each of the slices and re-flush the material
* forcing the GL texture of each slice in turn.
*
* XXX: It might also help if we could specify a texture matrix for code
* dealing with slicing that would be multiplied with the users own matrix.
*
* Normaly texture coords in the range [0, 1] refer to the extents of the
* texture, but when your GL texture represents a slice of the real texture
* (from the users POV) then a texture matrix would be a neat way of
* transforming the mapping for each slice.
*
* Currently for textured rectangles we manually calculate the texture
* coords for each slice based on the users given coords, but this solution
* isn't ideal, and can't be used with CoglVertexBuffers.
