38941372bf state: rename property "target-state" to "state"
This reduces the amount of typing, and should provide for more readable
code for most uses of ClutterState.

25509e6a7b Convert the ASCII art documentation in cogl-vertex-buffer to PNGs
The documentation for cogl_vertex_buffer_indices_get_for_quads was
using ugly ASCII art to draw the diagrams. These have now been
replaced with PNG figures.

86500cd3d5 Add CoglMaterialWrapMode to the Cogl docs and fix docs for the getters
CoglMaterialWrapMode was missing from the cogl-sections.txt file so it
wasn't getting displayed. There were also no documented return values
from the getters.

884df17536 Fix building the tesselator code for GLES
The tesselator code uses some defines that it expects to be in the GL
headers such as GLAPI and GLAPIENTRY. These are used to mark the entry
points as exportable on each platform. We don't really want the
tesselator code to use these but we also don't want to modify the C
files so instead they are #defined to be empty in the stub glu.h. That
header is only included internally when building the tesselator/ files
so it shouldn't affect the rest of Cogl.

GLES also doesn't have a GLdouble type so we just #define this to be a
regular double.

b74c722670 cogl-material: Don't doubly ref the parent in cogl_material_copy
cogl_material_copy was taking a reference on the original texture when
making a copy. However it then calls _cogl_material_set_parent on the
material which also takes a reference on the parent. The second
reference is cleaned up whenever _cogl_material_unparent is called and
this is also called by _cogl_material_free. However, it seems that
nothing was cleaning up the first reference. I think the reference is
entirely unnecessary so this patch removes it.

daf19205e0 align-constraint: Follow the position of the source
The AlignConstraint update is using only the width/height of the source,
but it should also take into account the position.

Also, instead of using the ::notify signal, it should follow the
BindConstraint, and switch to the ::allocation-changed signal, since
it's less expensive (one emission instead of four notifications, one for
each property we use).

534472a0d4 cogl: declare experimental symbols consistently
We had several different ways of exposing experimental API, in one case
the symbols had no special suffix, in two other ways the symbols were
given an _EXP suffix but in different ways.

This makes all experimental API have an _EXP suffix which is handled
using #defines in the header so the prototypes in the .c and .h files
don't have the suffix.

The documented reason for the suffix is so that anyone watching Cogl for
ABI changes who sees symbols disappear will hopefully understand what's
going on.

698743d454 cogl/tesselator: Update to the latest code from GLU
This grabs the latest code for libtess from git Mesa. This is mostly
so that we can get the following commit which fixes a lot of compiler
warnings in Clutter:

commit 75acb896c6da758d03e86f8725d6ca0cb2c6ad82
Author: Neil Roberts <neil@linux.intel.com>

    glu: Fix some compiler warnings in libtess
    
    When compiled with the more aggressive compiler warnings such as
    -Wshadow and -Wempty-body the libtess code gives a lot more
    warnings. This fixes the following issues:
    
    * The 'Swap' macro tries to combine multiple statements into one and
      then consume the trailing semicolon by using if(1){/*...*/}else.
      This gives warnings because the else part ends up with an empty
      statement. It also seems a bit dangerous because if the semicolon
      were missed then it would still be valid syntax but it would just
      ignore the following statement. This patch replaces it with the more
      common idiom do { /*...*/ } while(0).
    
    * 'free' was being used as a local variable name but this shadows the
      global function. This has been renamed to 'free_handle'
    
    * TRUE and FALSE were being unconditionally defined. Although this
      isn't currently a problem it seems better to guard them with #ifndef
      because it's quite common for them to be defined in other headers.

6341ba98f9 test-cogl-path: Add tests for changing the fill rule
This creates a path with an outer clockwise and two internal sub
paths, one clockwise and one counter-clockwise. The path is then

3a1456f34e cogl-path: Allow changing the fill rule
This adds two new API calls- cogl_path_set_fill_rule and
cogl_path_get_fill_rule. This allows modifying the fill rule of the
current path. In addition to the previous default fill rule of
'even-odd' it now supports the 'non-zero' rule. The fill rule is a
property of the path (not the Cogl context) so creating a new path or
preserving a path with cogl_path_get_handle affects the fill rule.

0cdbe7e098 cogl-path: Use the GLU tesselator to draw paths
Instead of drawing paths using the stencil buffer trick, it now
tesselates the path into triangles using the GLU tesselator and
renders them directly. A vbo is created with one vertex for each node
on the path. The tesselator is used to generate a series of indices
into the vbo as triangles. The tesselator's output of strips and fans
is converted into GL_TRIANGLES so that it can be rendered with a
single draw call (but the vertices are still shared via the
indices). The vbo is stored with the path so that if the application
uses retained paths then Cogl won't have to tessellate again.

The vertices also have texture coordinates associated with them so
that it can replicate the old behaviour of drawing a material with a
texture by fitting the texture to the bounding box of the path and
then clipping it. However if the texture contains waste or is sliced
then the vertex buffer code will refuse to draw it. In this case it
will revert back to drawing the path into the stencil buffer and then
drawing the material as a clipped quad.

The VBO is used even when setting up the stencil buffer for clipping
to a path because the tessellated geometry may cover less area.

The old scanline rasterizer has been removed because the tesselator
should work equally well on drivers with no stencil buffer.

fae4d60106 cogl: Pull in the code for GLU tesselator from Mesa/SGI
This copies the files for the GLU tesselator from Mesa. The Mesa code
is based on the original SGI code and is released under a BSD license.

The memalloc.h header has been replaced with one that forces the code
to use g_malloc and friends. The rest of the files are not altered
from the original so it should be possible to later upgrade the files
by simply overwriting them.

There is a tesselator.h header which is expected to be included by
rest of Cogl to use the tesselator. This contains a trimmed down
version of glu.h that only includes parts that pertain to the
tesselator. There is also a stub glu.h in the GL directory which is
just provided so that the tesselator code can include <GL/gl.h>
without depending on the system header. It just redirects to
tesselator.h

Attached patch contains a cookbook recipe about key press event

It covers both a simple approach (connecting a callback to a

modifiers), and a more complicated one based on a binding pool.

There's also some discussion of the two approaches.
