3336359abb [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.

53ba8bd92c [fixed-to-float-patches] Move the changes to gles2-wrapper.h into the patch
It looks like the changes to cogl-gles2-wrapper.h were accidentally
committed to the actual file instead of the patch in commit
de27da0e. This commit moves the changes back into the patch so
cogl-gles2-wrapper.h is reverted back to master.

eea3d2ce7c Merge branch 'master' into cogl-float
The patches have been updated to apply cleanly.

The patches for the g_warnings in clutter-actor.c have been removed
because master now uses CLUTTER_UNITS_FORMAT so they aren't
necessary. The clutter-units.h patch now sets CLUTTER_UNITS_FORMAT to
'f'.

7223b0a1a5 Fix GLES 2 after the multiple-texture-rectangle branch merge
The GLES 2 wrapper needs to set up some state before each
draw. Previously this was acheived by wrapping glDrawArrays. Since the
multiple-texture-rectangle branch merge, glDrawElements is used
instead so we also need a wrapper for that.

It was also directly calling glBindTexture. GLES 2 uses a wrapper for
this function so that it can cope with GL_ALPHA format textures. The
format of the current texture needs to be stored as well as the target
and object number for this to work.

1530be0af9 Merge branch multiple-texture-rectangle into master
Bug 1289 - Draw multiple glyphs at once

The multiple-texture-rectangle branch adds a new Cogl texture function
called cogl_texture_multiple_rectangles which is used to draw multiple
rectangles out of a texture using a single GL call. This is
significantly faster than drawing the rectangles with individual calls
on some platforms. The Pango renderer now uses this to speed up
rendering.

The conflicts are just due to the whitespace fixes in cb569a5.

b6470ab900 [cogl-material] Restore the GL_TEXTURE_ENV_MODE after material_rectangle
The rest of Cogl expects the texture mode to be GL_MODULATE so it

cogl_texture_rectangle will fail to blend with the Cogl color properly

0408a5d2c5 [cogl-material] improvements for cogl_material_rectangle
The API has been changed to take an explicit length for the number of
texture coordinates passed, and it's now documented that if there are
more layers to the current material than the number of texture coords
passed, then default coordinates will be generated for the other
layers.

cogl_material_rectangle should now handle the case where a single
sliced texture is supplied as a material layer by falling back to
cogl_texture_rectangle. We are nearly at the point that
cogl_texture_rectangle could be deprecated. A few issues remain
though, such as not considering waste in cogl_material_rectangle.

98bd85afaa [cogl-material] Adds a cogl_material_set_color function
The other colors of a material; such as the ambient and diffuse color are
only relevent when we can enable lighting. This adds a basic unlit
color property.

Later cogl_set_source_color can be integrated to either modify the color
of the current source material, or maintain a special singlton CoglMaterial
that is modified by calls to cogl_set_source_color and implicitly made
current.

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.
