This adds a library that can be used instead of libGLESv2.so to provide
symbols for the GLES 2.0 api. This can be used for convenience when
using the cogl_gles2_context_ api since you don't need to manually go
through a CoglGLES2Vtable when calling the gles2 api so it should be
easier to port existing gles2 code to integrate with Cogl.

This makes it possible to integrate existing GLES2 code with
applications using Cogl as the rendering api.
Currently all GLES2 usage is handled with separate GLES2 contexts to
ensure that GLES2 api usage doesn't interfere with Cogl's own use of
OpenGL[ES]. The api has been designed though so we can provide tighter
integration later.
The api would allow us to support GLES2 virtualized on top of an
OpenGL/GLX driver as well as GLES2 virtualized on the core rendering api
of Cogl itself. Virtualizing the GLES2 support on Cogl will allow us to
take advantage of Cogl debugging facilities as well as let us optimize
the cost of allocating multiple GLES2 contexts and switching between
them which can both be very expensive with many drivers.
As as a side effect of this patch Cogl can also now be used as a
portable window system binding API for GLES2 as an alternative to EGL.
Parts of this patch are based on work done by Tomeu Vizoso
<tomeu.vizoso@collabora.com> who did the first iteration of adding GLES2
API support to Cogl so that WebGL support could be added to
webkit-clutter.
This patch adds a very minimal cogl-gles2-context example that shows how
to create a gles2 context, clear the screen to a random color and also
draw a triangle with the cogl api.

This fixes a bug in _cogl_pipeline_flush_color_blend_alpha_depth_state
whereby we were only calling flush_depth_state if we knew that at least
depth testing was enabled. This didn't take into account that enabling
and disabling depth writing is a useful change to make even if depth
testing is disabled. It also seemed a bit messy to flush the
depth-testing enable separately from the other depth state.
_cogl_pipeline_flush_color_blend_alpha_depth_state now simply calls
flush_depth_state() if there is a _DEPTH_STATE difference and
flush_depth_state() also handles flushing the depth-testing enable
in along with all the other depth state.

The function to convert the CoglBufferUpdateHint to a GL enum was

trying to use it on GLES1 if support for both is compiled. The other
problem is that GLES2 seems to actually support GL_STREAM_DRAW so we
might as well use it in that case.
This patch also changes it so that if the hint is stream with GLES1

Cogl has feature flags for basic npot texture support and then separate
flags for npot + repeat and npot + mipmap. If those three features are
available then there is a feature for full-npot support too for
convenience. The cogl_texture_2d_new_ constructors were checking for
full npot support and failing if not available but since we expose the
fine grained features to the user the user should be able to check the
limitations of npot textures and still choose to allocate them.
_cogl_texture_2d_can_create() now only checks for basic npot support
when creating a npot texture. Since this change also affects the
automagic cogl_texture_ constructors they now check for basic npot +
mipmap support before considering using a Texture2D.
Notably the cogl_texture_ constructors will try constructing a Texture2D
even if we don't have npot + repeat support since the alternative is a
sliced texture which will need manual repeating anyway. Accordingly the
Texture2D::can_hardware_repeat and ::transform_quad_coords_to_gl vfuncs
have been made aware of the npot + repeat feature flag.

This adds a version header which contains macros to define which
version of Cogl the application is being compiled against. This helps
applications that want to support multiple incompatible versions of
Cogl at compile time.
The macros are called COGL_VERSION_{MAJOR,MINOR,MICRO}. This does not
match Clutter which names them CLUTTER_{MAJOR,MINOR,MICRO}_VERSION but
I think the former is nicer and it at least matches Cairo and Pango.
The values of the macro are defined to COGL_VERSION_*_INTERNAL which
is generated by the configure script into cogl-defines.h.
There is also a macro for the entire version as a string called
COGL_VERSION_STRING.
The internal utility macros for encoding a 3 part version number into
a single integer have been moved into the new header so they can be
used publicly as a convenient way to check if the version is within a
particular range. There is also a COGL_VERSION_CHECK macro for the
very common case that a feature will be used since a particular
version of Cogl. There is a macro called COGL_VERSION which contains
the pre-encoded version of Cogl being compiled against for
convenience.
Unlike in Clutter this patch does not add any runtime version
identification mechanism.
A test case is also added which just contains static asserts to sanity
check the macros.

This re-designs the matrix stack so we now keep track of each separate
operation such as rotating, scaling, translating and multiplying as
immutable, ref-counted nodes in a graph.
Being a "graph" here means that different transformations composed of
a sequence of linked operation nodes may share nodes.
The first node in a matrix-stack is always a LOAD_IDENTITY operation.
As an example consider if an application where to draw three rectangles
A, B and C something like this:
cogl_framebuffer_scale (fb, 2, 2, 2);
cogl_framebuffer_push_matrix(fb);
cogl_framebuffer_translate (fb, 10, 0, 0);
cogl_framebuffer_push_matrix(fb);
cogl_framebuffer_rotate (fb, 45, 0, 0, 1);
cogl_framebuffer_draw_rectangle (...); /* A */
cogl_framebuffer_pop_matrix(fb);
cogl_framebuffer_draw_rectangle (...); /* B */
cogl_framebuffer_pop_matrix(fb);
cogl_framebuffer_push_matrix(fb);
cogl_framebuffer_set_modelview_matrix (fb, &mv);
cogl_framebuffer_draw_rectangle (...); /* C */
cogl_framebuffer_pop_matrix(fb);
That would result in a graph of nodes like this:
LOAD_IDENTITY
|
SCALE
/ \
SAVE LOAD
| |
TRANSLATE RECTANGLE(C)
| \
SAVE RECTANGLE(B)
|
ROTATE
|
RECTANGLE(A)
Each push adds a SAVE operation which serves as a marker to rewind too
when a corresponding pop is issued and also each SAVE node may also
store a cached matrix representing the composition of all its ancestor
nodes. This means if we repeatedly need to resolve a real CoglMatrix
for a given node then we don't need to repeat the composition.
Some advantages of this design are:
- A single pointer to any node in the graph can now represent a
complete, immutable transformation that can be logged for example
into a journal. Previously we were storing a full CoglMatrix in
each journal entry which is 16 floats for the matrix itself as well
as space for flags and another 16 floats for possibly storing a
cache of the inverse. This means that we significantly reduce
the size of the journal when drawing lots of primitives and we also
avoid copying over 128 bytes per entry.
- It becomes much cheaper to check for equality. In cases where some
(unlikely) false negatives are allowed simply comparing the pointers
of two matrix stack graph entries is enough. Previously we would use
memcmp() to compare matrices.
- It becomes easier to do comparisons of transformations. By looking
for the common ancestry between nodes we can determine the operations
that differentiate the transforms and use those to gain a high level
understanding of the differences. For example we use this in the
journal to be able to efficiently determine when two rectangle
transforms only differ by some translation so that we can perform
software clipping.

This adds a very minimal and fast allocator for chunks of memory of a
predetermined size. This has some similarities to the glib slice
allocator although notably it is not thread safe and instead of
internally tracking multiple magazines for various sized allocations the
api lets you explicitly allocate a single magazine for a single specific
size and a pointer to the magazine is passed explicitly to the allocate
and free functions.
This allocator builds on the CoglMemoryStack allocator as an underlying
heap allocator and just never rewinds the stack. This means the heap is
effectively a grow only linked list of malloc()'d blocks of memory.
A CoglMagazine tracks a singly linked list of chunks of a predetermined
size and _cogl_magazine_chunk_alloc() simply unlinks and returns the
head of the list. If the list is empty it falls back to allocating from
the underlying stack.
_cogl_magazine_chunk_free() links the chunk back into the singly linked
list for re-use.
The chunk size passed to _cogl_magazine_new() is automatically rounded
to a multiple of 8 bytes to ensure that all stack allocations end up
aligned to 8 bytes. This also ensures that when a chunk is freed then it
will be large enough to store a pointer to the next free chunk as part
of a singly linked list.

This adds a very minimal internal allocator api that lets us create a
dynamically growable (grow only) stack.
Underlying the allocator is the idea of "sub stacks" which are simply
malloc()'d chunks of memory kept in a linked list. The stack itself
maintains a pointer to the current sub-stack and a current
sub-stack-offset. 99% of the time allocating from the stack is just a
case of returning a pointer to the current sub-stack + sub-stack-offset
and bumping the offset by the allocation size. If there isn't room in
the current sub-stack then we walk through the list of free sub-stacks
looking for one that's big enough for the allocation and if we reach the
end of the list then we allocate a new sub-stack twice as big as the
last (or twice as big as the requested allocation if that's bigger).
Since it's a stack model there is no api to free allocations, just a
function to rewind the stack to the beginning.
We expect this to be useful in multiple places in Cogl as an extremely
fast allocator in cases when we know we can scrap all the allocations
after we're done figuring something out or as a building block for
other allocators.
For example the tessellator used for CoglPath allocates lots of tiny
structures that can all be freed after tessellation.

The coding style has for a long time said to avoid using redundant glib

code look unnecessarily foreign to developers coming from outside of the
Gnome developer community.
Note: When we tried to find the historical rationale for the types we
just found that they were apparently only added for consistent syntax
highlighting which didn't seem that compelling.
Up until now we have been continuing to use some of the platform
specific type such as gint{8,16,32,64} and gsize but this patch switches
us over to using the standard c99 equivalents instead so we can further
ensure that our code looks familiar to the widest range of C developers
who might potentially contribute to Cogl.
So instead of using the gint{8,16,32,64} and guint{8,16,32,64} types this
