016005591d cogl-matrix-stack: Convert to be a CoglObject
We will want to use ref-counting on the CoglMatrixStack so it might as
well be a CoglObject.

58a2261387 matrix-stack: Make header style consistent
Cogl doesn't follow the Clutter/GTK+ columnized function prototype style
so this updates cogl-matrix-stack.h to match the other Cogl headers.

4976d22940 matrix-stack: Adds a stack age counter
Sometimes it would be useful if we could efficiently track when a matrix
stack has been modified. For example on GLES2 we have to upload the
modelview as a uniform to our glsl programs but because the modelview
state is part of the framebuffer state it becomes a bit more tricky to
know when to re-sync the value of the uniform with the framebuffer
state. This adds an "age" counter to CoglMatrixStack which is
incremented for any operation that effectively modifies the top of the
stack so now we can save the age of the stack inside the pipeline
whenever we update modelview uniform and later compare that with the
stack to determine if it has changed.

856d43a27c cogl-pipeline: Add internal API to get the layer matrix
This returns the layer matrix given a pipeline and a layer index. The
API is kept as internal because it directly returns a pointer into the
layer private data to avoid a copy into an out-param. We might also
want to add a public function which does the copy.

4514d49dda cogl-vertex-attribute: Use glVertexAttribPointer on GLES2
When the GLES2 wrapper is removed we can't use the fixed function API
such as glColorPointer to set the builtin attributes. Instead the GLSL
progend now maintains a cache of attribute locations that are queried
with glGetAttribLocation. The code that previously maintained a cache
of the enabled texture coord arrays has been modified to also cache
the enabled vertex attributes under GLES2. The vertex attribute API is
now the only place that is using this cache so it has been moved into
cogl-vertex-attribute.c

1515a8d73a cogl-path: Stroke using the vertex attribute API
Previously when stroking a path it was flushing a pipeline and then
directly calling glDrawArrays to draw the line strip from the path
nodes array. This patch changes it to build a CoglVertexArray and a
series of attributes to paint with instead. The vertex array and
attributes are attached to the CoglPath so it can be reused later. The
old vertex array for filling has been renamed to fill_vbo.

3c5fa0cf90 cogl: Move COGL_DEBUG=show-source into cogl-shader.c
The code to display the source when the show-source debug option is
given has been moved to _cogl_shader_set_source_with_boilerplate so
that it will show both user shaders and generated shaders. It also
shows the code with the full boilerplate. To make it the same for
ARBfp, cogl_shader_compile_real now also dumps user ARBfp shaders.

8764a0d487 cogl: Add a vertend to generate GLSL
The GLSL vertend is mostly only useful for GLES2. The fixed function
vertend is kept at higher priority than the GLSL vertend so it is
unlikely to be used in any other circumstances.

6c34fb7232 cogl-shader-boilerplate: Don't put the color attrib in location 0
Due to Mesa bug 28585 calling glVertexAttrib with attrib location 0
doesn't appear to work. This patch just reorders the vertex and color
attributes in the shader in the hope that Mesa will assign the color
attribute to a different location.

cf0ded1361 cogl-shader-boilerplate: Add more builtins for GLES2
Some builtin attributes such as the matrix uniforms and some varyings
were missing from the boilerplate for GLES2. This also moves the
texture matrix and texture coord attribute declarations to
cogl-shader.c so that they can be dynamically defined depending on the
number of texture coord arrays enabled.

a3e53dd029 cogl: Add a fixed function vertend
The vertends are intended to flush state that would be represented in
a vertex program. Code to handle the layer matrix, lighting and
point size has now been moved from the common cogl-pipeline-opengl
backend to the fixed vertend.

313adc7bdf cogl: Add a GLSL 'progend'
'progend' is short for 'program backend'. The progend is intended to
operate on combined state from a fragment backend and a vertex
backend. The progend has an 'end' function which is run whenever the
pipeline is flushed and the two pipeline change notification
functions. All of the progends are run whenever the pipeline is
flushed instead of selecting a single one because it is possible that
multiple progends may be in use for example if the vertends and
fragends are different. The GLSL progend will take the shaders
generated by the fragend and vertend and link them into a single
program. The fragend code has been changed to only generate the shader
and not the program. The idea is that pipelines can share fragment
shader objects even if their vertex state is different. The authority
for the progend needs to be the combined authority on the vertend and
fragend state.

1e3cdb60d6 cogl-program: Add private functions to check if have each shader type
This adds two internal functions:

gboolean
_cogl_program_has_fragment_shader (CoglHandle handle);

gboolean
_cogl_program_has_vertex_shader (CoglHandle handle);

They just check whether any of the contained shaders are of that type.

31f0eb4f71 cogl-pipeline: Make find codegen authority more general
The pipeline function _cogl_pipeline_find_codegen_authority has been
renamed to _cogl_pipeline_find_equivalent_parent and it now takes a
set of flags for the pipeline and layer state that affects the
authority. This is needed so that we can reuse the same code in the
vertend and progends.

a1996706a2 cogl-pipeline: Move texture enabling/disabling to fixed fragend
Previously enabling and disabling textures was done whatever the
backend in cogl-pipeline-opengl. However enabling and disabling
texture targets only has any meaning if no fragment shaders are being
used so this patch moves the code to cogl-pipeline-fragend-fixed.

The GLES2 wrapper has also been changed to ignore enabledness when
deciding whether to update texture coordinate attribute pointers.

952878aab1 Rename CoglPipelineBackend to CoglPipelineFragend
The current Cogl pipeline backends are entirely concerned with the
fragment processing state. We also want to eventually have separate
backends to generate shaders for the vertex processing state so we
need to rename the fragment backends. 'Fragend' is a somewhat weird
name but we wanted to avoid ending up with illegible symbols like
CoglPipelineFragmentBackendGlslPrivate.

54db48dfd1 animation: Allow transforming values in bind()
While we do check for compatibility and transformability of a GValue
with the GParamSpec value type, we are actually failing really badly
at it.

First of all, we bail out on the wrong conditions.

Then we use the type of the value passed instead of using the type
of the property itself.

This makes it impossible to actually use transformation functions for
GValue types - even those that have been registered by GLib itself -
when using the Animation API directly, instead of going through the
clutter_actor_animate() wrappers.

ae4e06d8c4 introspection: Skip some C-only structures
The ParamSpec sub-classes we define are meant to be used only from the C
API, as high-level languages completely ignore them.

The ClutterStageWindow interface is an internal type that escaped into
the public headers; all its methods are private, but we cannot remove
the type until we break for 2.0.

d8515bf429 Fix clutter_list_model_get_iter_at_row() when filtered
Currently clutter_list_model_get_iter_at_row() always returns an
iterator to the last non-filtered row  when asking for row [1-N].

Patch makes the function return an iterator to the Nth non-filtered
row or NULL.

46295a0dd1 arbfp: Copy pipelines used as cache keys
We are currently using a pipeline as a key into our arbfp program cache
but because we weren't making a copy of the pipelines used as keys there
were times when doing a lookup in the cache would end up trying to
compare a lookup key with an entry key that would point to invalid
memory.

Note: the current approach isn't ideal from the pov that that key
pipeline may reference some arbitrarily large user textures will now be
kept alive indefinitely. The plan to improve on this is that we will
have a mechanism to create a special "key pipeline" which will derive
from the default Cogl pipeline (to avoid affecting the lifetime of
other pipelines) and only copy state from the original pipeline that
affects the arbfp program and will reference small dummy textures
instead of potentially large user textures.

bac600b21b pipeline: Clarify stages for finding an arbfp program
In the arbfp backend there is a seqential approach to finding a suitable
arbfp program to use for a given pipeline; first we see if there's
already a program associated with the pipeline, 2nd we try and find a
program associated with the "arbfp-authority" 3rd we try and lookup a
program in a cache and finally we resort to starting code-generation for
a new program. This patch slightly reworks the code of these steps to
hopefully make them a bit clearer.

ea66156c83 pipeline: don't use near/far symbols
According to 9cc9033347 the windows headers #define near as nothing,
and presumable the same is true for 'far' too. Apparently this define is
to improve compatibility with code written for Windows 3.1, so it's good
that people will be able to incorporate such code into their Clutter

ca7dc2f951 cogl-backend-egl: Chain up to the X11 backend init_events
Since c6493885c3 when building the EGL backend for eglx there was
no fallback in the init_events implementation so the X11 backend init
function would never get called. This was stopping it from receiving
any X events so a lot of things broke. It now just chains up.

f8fc194b3b clutter-score: Initialize ClutterScoreEntry::complete_id
When clutter_score_append_at_marker is called instead of
clutter_score_append the complete_id field of ClutterScoreEntry was
being left uninitialised. When the entry is eventually freed it would
sometimes try to disconnect an invalid signal id. This was causing
conformance test failures for me on GLES2.

9d836d8ce5 context: only declare arbfp cache for GL
We were trying to declare and initializing an arbfp program cache for
GLES but since the prototypes for the _hash and _equal functions were
only available for GL this broke the GLES builds. By #ifdefing the code
to conditionally declare/initialize for GL only this should hopefully
fix GLES builds.

464ed7e6b7 arbfp: Adds an ARBfp program cache
This adds a cache (A GHashTable) of ARBfp programs and before ever
starting to code-generate a new program we will always first try and

cc36e49ec5 pipeline: generalize _cogl_pipeline_equal
_cogl_pipeline_equal now accepts a mask of pipeline differences and layer
differences to constrain what state will be compared. In addition a set
of flags are passed that can tweak the comparison semantics for some
state groups. For example when comparing layer textures we sometimes
only need to compare the texture target and can ignore the data itself.

In updating the code this patch also changes it so all required pipeline
authorities are resolved in one step up-front instead of resolving the
authority for each state group in turn and repeatedly having to traverse
the pipeline's ancestry. This adds two new functions
_cogl_pipeline_resolve_authorities and
_cogl_pipeline_layer_resolve_authorities to handle resolving a set of
authorities.
