0e5df17761 doc: Fix EXTRA_DIST variable setup
Since gtk-doc is an optional dependency for Cogl then we need to special
case how EXTRA_DIST is initialized. It shouldn't be set when using
gtk-doc since gtk-doc.make expects to initialize EXTRA_DIST.  If we
aren't using gtk-doc then it should be initialized to an empty value
instead of including gtk-doc.make so that the later lines that append
various extra png files to EXTRA_DIST won't fail.

800f5e6d6e profile: Adds a --enable-profile option
This adds a --enable-profile option which enables uprof based profiling.
It was also necessary to fixup a CLUTTER_ENABLE_PROFILING #ifdef in
cogl-context.c to renamed COGL_ENABLE_PROFILING instead. By default Cogl
doesn't output uprof reports directly, instead it assumes a higher level
toolkit will output a report. If you want a report from Cogl you can
export COGL_PROFILE_OUTPUT_REPORT=1 before running your app.

The latest version of uprof can be fetched from:

3729bf2769 Make it clearer that the 2.0 API is experimental
This explicitly renames the cogl-2.0 reference manual to
cogl-2.0-experimental and renames the cogl-2.0 pkg-config file to
cogl-2.0-experimental.pc. Hopefully this should avoid
miss-understandings.

a9643f38e6 x11-foreign: explicitly pass -lX11 ldflag
The x11-foreign example directly uses the X11 API at it seems that more
recent versions of binutils complain if we don't directly link the test
with libX11 as opposed to relying on indirect linkage via cogl.

e86543cd7d Revert "Do not use "near" and "far" variables"
This reverts commit 3d2564df8f.

Since 01e1260aa the 'near' and 'far' defines are now undef'd on

01e1260aa0 configure: Force #undef of 'near' and 'far' on Windows
This adds an extra header that gets included from config.h where we

when building for Windows so that we don't have to avoid using them as
variable names in the Cogl code.

c603dc67ca cogl-vertex-buffer: make sure to unref weak pipelines
When validating a user pipeline before drawing with a CoglVertexBuffer
we sometimes find we have to make some overrides and we handle that by
creating a pipeline which is a weak copy of the user pipeline. The weak
pipeline gets associated with the original pipeline so if that pipeline
is used multiple times then we can re-use the same override pipeline and
skip validation. Because it's a weak pipeline we get notified when the
original material is destroyed or changed so we know our weak pipeline
is now invalid.

When we get notified that the weak material is invalid we should unref
it, but instead we were just discarding our reference to it. This was
resulting in leaking weak materials and in some cases those materials
referenced textures which would then also be leaked.

db954565d4 cogl-pango-render: Use the glyph size for unknown glyphs
When rendering a box for an unknown glyph it would previously just use
the average glyph size for the font. This causes problems because the
size calculations for the layout assume a different size so it can end
up rendering outside of the expected ink rectangle. This patch changes
it to query the size of the glyph in the font. Pango should end up
reporting the size of what would be the hex box which should be the
same as the sized used for the extents calculation.

c3c0804819 Implement COGL_DEBUG=disable-texturing for ARBFp and GLSL fragends
The COGL_DEBUG=disable-texturing debug variable disables texturing in
the fixed function fragend by not bothering to enable the texture
targets. This wasn't working for the programmable fragends because the
texture targets don't need to be enabled to use them. This patch
modifies the two programmable backends to generate a constant value
for the texture lookups in the shader when the debug variable is
given.

5022ec54d2 replace _xlib_add_filter use with _cogl_renderer API
Instead of using _cogl_xlib_add/remove_filter we now use
_cogl_renderer_add/remove_native_filter. The _cogl_xlib_add_filter API
was only required as a stop gap while EGL support was still in Clutter
because in that case we were using the stub winsys and didn't have a
CoglRenderer.

These were originally only required while the EGL winsys was being
handled in clutter and so there wasn't a CoglRenderer in all cases.

43c4b21a1d Adds an example cogl wayland compositor
This adds an example cogl compositor to test the
_cogl_wayland_texture_2d_new_from_buffer API. The compositor emulates 4
output displays but doesn't support input since Cogl doesn't deal with
input. It's quite a minimal example of what it takes to write a wayland
compositor so could be interesting to anyone learning about wayland.

b934859dde renderer: set winsys on renderer before ->renderer_connect
When iterating through all the possible window systems trying to find
one we can successfully connect we now associated the current winsys
vtable with the renderer before calling winsys->renderer_connect in case
the implementation calls some other Cogl API that expects to be able to
determine the current winsys. For example calling _cogl_get_proc_address
when querying winsys extensions as part of a successful connect will
need to get at the current winsys vtable.

if Cogl should support this feature and potentially any EGL based winsys

EGL_WL_bind_display extensions.

b380fed23d Make stub winsys into a proper winsys backend
Instead of the stub winsys being a special case set of #ifdef'd code
used when COGL_HAS_FULL_WINSYS wasn't defined, the stub winsys now
implements a CoglWinsysVtable like all other winsys backends (it's just
that everything is a NOP). This way we can get rid of the
COGL_HAS_FULL_WINSYS define and also the stub winsys can be runtime
selected whereas before it was incompatible with all other winsys
backends.

ee7cc9e788 Make CoglTexture2D public as experimental API
This exposes a CoglTexture2D typedef and adds the following experimental
API:
    cogl_is_texture_2d
    cogl_texture_2d_new_with_size
    cogl_texture_2d_new_from_data
    cogl_texture_2d_new_from_foreign

Since this is experimental API you need to define
COGL_ENABLE_EXPERIMENTAL_API before including cogl.h.

Note: With these new entrypoints we now expect a CoglContext pointer to
be passed in, instead of assuming there is a default context. The aim is
that for Cogl 2.0 we won't have a default context so this is a step in
that direction.

1e3f4f62e0 framebuffer: validate width/height in _set_viewport
This validates that the viewport width and height arguments are positive
values in _cogl_framebuffer_set_viewport. In addition, just before
calling glViewport we also assert that something else hasn't gone amiss
and that the internal viewport width/height values we track are still
positive before passing to glViewport which generates an error for
negative values.

5a9b92a4a5 Revert "Initial build of a Quartz winsys stub"
This reverts commit b2e41f1bfa.

We are backing out the quartz specific stub winsys since we can simply
use the generic stub winsys on quartz until we develop a standalone
winsys. Since we plan on removing all special cases for the stub winsys
by handling with a winsys vtable like all the others it's better if we
don't introduce a quartz specific stub.

efadc439a4 cogl-journal: Use a pool of vertex arrays
Previously whenever the journal is flushed a new vertex array would be
created to contain the vertices. To avoid the overhead of reallocating
a buffer every time, this patch makes it use a pool of 8 buffers which
are cycled in turn. The buffers are never destroyed but instead the
data is replaced. The journal should only ever be using one buffer at
a time but we cache more than one buffer anyway in case the GL driver
is internally using the buffer in which case mapping the buffer may
cause it to create a new buffer anyway.

54f94a0ed0 cogl-pipeline-fragend-fixed: Fix enabling texture targets
When flushing a pipeline that has more layers than the previous
pipeline, the fixed function fragend is supposed to detect that the
texture unit previously had no texture target enabled and then enable
it. However the logic for checking whether the unit was enabled was
broken due to a typing failure when unit->enabled and
unit->current_gl_target were combined into one value in commit
6b7139b0. This was breaking some of the conformance tests when the
fixed function fragend is used.

d8df30cb9c cogl-pipeline-opengl: Don't use number of tex units on fixed-function
The CoglPipeline code uses a combination of GL_MAX_TEXTURE_COORDS,
GL_MAX_COMBINED_TEXTURE_IMAGE_UNITS and GL_MAX_TEXTURE_UNITS to
determine the maximum number of layers to allow in a pipeline. However
on fixed function hardware that doesn't advertise either GLSL or ARBfp
it was still using the first two enums which will probably just return
0 and set a GLerror. This meant that we effectively didn't support
using any layers on purely fixed function hardware. This patch changes
it to only use those two enums if the appropriate extensions are
advertised and to always use GL_MAX_TEXTURE_UNITS except on GLES2
where there is no fixed function.
