e2fcb62990 journal: Fixes logging of multiple sets of texture coordinates
If a user supplied multiple groups of texture coordinates with
cogl_rectangle_with_multitexture_coords() then we would repeatedly log only
the first group in the journal.  This fixes that bug and adds a conformance
test to verify the fix.

Thanks to Gord Allott for reporting this bug.

9690913fef cogl: Support multiple fallbacks in cogl_offscreen_new_to_texture()
The Intel drivers in Mesa 7.6 (and possibly earlier versions) don't
support creating FBOs with a stencil buffer but without a depth
buffer. This reworks framebuffer allocation so that we try a number
of fallback options before failing.

The options we try in order are:
- the same options that were sucessful last time if available
- combined depth and stencil
- separate depth and stencil
- just stencil, no depth
- just depth, no stencil
- neither depth or stencil

05ce533fc8 framebuffers: cogl_offscreen_new_to_texture should take a ref on the texture
We weren't taking a reference on the texture to be used as the color buffer
for offscreen rendering, so it was possible to free the texture leaving the
framebuffer in an inconsistent state.

fbad0a75b6 profiling: Adds initial UProf accounting to Cogl
This adds gives Cogl a dedicated UProf context which will be linked together
with Clutter's context during clutter_init_real().

Initial timers cover _cogl_journal_flush and _cogl_journal_log_quad

You can explicitly ask for a report of Cogl statistics by exporting
COGL_PROFILE_OUTPUT_REPORT=1 but since the context is linked with Clutter's
the statisitcs will also be shown in the automatic Clutter reports.

If we are using GL* types we should also be including cogl-defines.h, as
that will include the right GL header.

5441440f47 cogl: Use #ifdef GL around GL_TEXTURE_RECTANGLE_ARB
Commit 558b17ee1e added support for rectangle textures to the
framebuffer code. Under GLES there is no GL_TEXTURE_RECTANGLE_ARB
definition so this was breaking the build. The rest of Cogl uses
ifdef's around that constant so we should do the same here.

a8b563b622 cogl: Enable blending if a lighting colour is semi-transparent
We currently enable blending if the material colour has
transparency. This patch makes it also enable blending if any of the
lighting colours have transparency. Arguably this isn't neccessary
because we don't expose any API to enable lighting so there is no
bug. However it is currently possible to enable lighting with a direct
call to glEnable and this otherwise works so it is a shame not to have
it.

944423a8d9 cogl: deprecate cogl_draw_buffer API and replace with a cogl_framebuffer API
cogl_push_draw_buffer, cogl_set_draw_buffer and cogl_pop_draw_buffer are now
deprecated and new code should use the new cogl_framebuffer_* API instead.

Code that previously did:
    cogl_push_draw_buffer ();
    cogl_set_draw_buffer (COGL_OFFSCREEN_BUFFER, buffer);
    /* draw */
    cogl_pop_draw_buffer ();
should now be re-written as:
    cogl_push_framebuffer (buffer);
    /* draw */
    cogl_pop_framebuffer ();

As can be seen from the example above the rename has been used as an
opportunity to remove the redundant target argument from
cogl_set_draw_buffer; it now only takes one call to redirect to an offscreen
buffer, and finally the term framebuffer may be a bit more familiar to
anyone coming from an OpenGL background.

1df0e36c6c cogl: Use a vtable for the texture backends instead of a type and switch
Instead of storing an enum with the backend type for each texture and
then using a switch statement to decide which function to call, we
should store pointers to all of the functions in a struct and have
each texture point to that struct. This is potentially slightly faster
when there are more backends and it makes implementing new backends
easier because it's more obvious which functions have to be
implemented.

95fed739d5 offscreen: cogl_offscreen_new_to_texture now supports GL_TEXTURE_RECTANGLE_ARB
cogl_offscreen_new_to_texture previously bailed out if the given texture's

foreign GL_TEXTURE_RECTANGLE_ARB textures.

16a09763ef [cogl-material] Adds cogl_material_copy() API
cogl_material_copy can be used to create a new CoglHandle referencing a copy
of some given material.

From now on we will advise that developers always aim to use this function
instead of cogl_material_new() when creating a material that is in any way
derived from another.

By using cogl_material_copy, Cogl can maintain an ancestry for each material
and keep track of "similar" materials.  The plan is that Cogl will use this
information to minimize the cost of GPU state transitions.

d2ce4f7137 docs: Don't document cogl_flush_gl_state as public API
This function was #if 0'd before we released Clutter 1.0 so there's no
implementation of it.  At some point we thought it might assist with
developers breaking out into raw OpenGL.  Breaking out to raw GL is a
difficult problem though so we decided instead we will wait for a specific
use case to arrise before trying to support it.

d2f8f6c581 Minor fix to cogl material
_cogl_material_get_layer expects a CoglMaterial* pointer but it was
being called with a CoglHandle. This doesn't matter because the
CoglHandle is actually just the CoglMaterial* pointer anyway but it
breaks the ability to change the _cogl_material_pointer_from_handle
macro.

2f2c3fb839 build: Make cogl.h not conditional on driver defines
The main COGL header cogl.h is currently created at configure time
because it conditionally includes the driver-dependent defines. This
sometimes leads to a stale cogl.h with old definitions which can
break the build until you clean out the whole tree and start from
scratch.

We can generate a stable cogl-defines.h at build time from the
equivalent driver-dependent header and let cogl.h include that
file instead.
