26f07abc65 [cogl-material] Allow setting a layer with an invalid texture handle
It was previously possible to create a material layer with no texture
by setting some property on it such as the matrix. However it was not
possible to get back to that state without removing the layer and
recreating it. It is useful to be able to remove the texture to free
resources without forgetting the state of the layer so we can put a
different texture in later.

fa0b33ec30 [clutter-stage-win32] Call clutter_actor_map instead of setting the flags
The clutter_actor_map and unmap functions need to be called to

6825b9db1c [actor] Unrealize on destroy
If the application code calls for destruction of an actor we need
to make sure that the actor is unrealized before running the dispose
sequence; otherwise, we might trigger an assertion failure on composite
actors.

762873e79e [master clock] Avoid excessive redraws
Currently, the clock source spins a redraw every time there is at
least a timeline running. If the timelines were not advanced in
the previous frame, though, because their interval is larger than
the vblanking interval then this will lead to excessive redraws of
the scenegraph even if nothing has changed.

To avoid this a simple guard should be set by the MasterClock::advance
method in case no timeline was effectively advanced, and checked
before dispatching the stage redraws.

bd13a4ddc4 [color] Add support for the "#rgba" color format
clutter_color_from_string() only supported the "#rrggbbaa" format with
alpha channel, this patch adds support for "#rgba".

Colors in "#rrggbb" format were parsed manually, this is now left to
the pango color parsing fallback, since that's handling it just fine.

ffd5fb172b [docs] Rework the API reference version generation
Clutter copies the gtk-doc from the usual gtk+ template, and
has a version.xml.in containing only:

  @VERSION@

Without a newline at the end. Unfortunately, it appears that
autoconf has started adding a newline to the generated version.xml
which then is used as the payload for the "version" XML entity.

Instead of using a secondary file we can make configure generate
the whole clutter-docs.xml and cogl-docs.xml files from a template;
this way we also get the ability to substitute more autoconf variables
into the documentation -- if needs be.

61deeafa71 [cogl-shader] Make get_info_log() slightly nicer
The cogl_shader_get_info_log() function is very inconvenient for
language bindings and for regular use, as it requires a static
buffer to be filled -- basically just providing a wrapper around
glGetInfoLogARB().

Since COGL aims to be a more convenient API than raw GL we should
just make cogl_shader_get_info_log() return an allocated string
with the GLSL compiler log.

5c26cc6ba7 Use GL_QUADS for flushing a quad batch
Instead of using GL_TRIANGLES and uploading the indices every time, it
now uses GL_QUADS instead on OpenGL. Under GLES it still uses indices
but it uses the new cogl_vertex_buffer_indices_get_for_quads function
to avoid uploading the vertices every time.

This requires the _cogl_vertex_buffer_indices_pointer_from_handle
function to be exposed privately to the rest of Cogl.

The static_indices array has been removed from the Cogl context.

c759aeb6a7 Uniformly use floats in Actor properties
All the underlying implementation and the public entry points have
been switched to floats; the only missing bits are the Actor properties
that deal with positioning and sizing.

This usually means a major pain when dealing with GValues and varargs
functions. While GValue will warn you when dealing with the wrong
conversions, varags will simply die an horrible (and hard to debug)
death via segfault. Nothing much to do here, except warn people in the
release notes and hope for the best.

indices needed to render using pairs of GL_TRIANGLES. The VBO is

4afe1e9a8b [actor] Add allocate_available_size()
The allocate_available_size() method is a convenience method in
the same spirit as allocate_preferred_size(). While the latter
will allocate the preferred size of an actor regardless of the
available size provided by the actor's parent -- and thus it's
suitable for simple fixed layout managers like ClutterGroup -- the
former will take into account the available size provided by the
parent and never allocate more than that; it is, thus, suitable
for simple fluid layout managers.

63c7cc0175 [master clock] Handle Timeline::started signal correctly
The "started" signal is sent first after the timeline has been set to the
'running' state. For this reason, checking if the clock has any running
timelines running will always return true in the "started" signal handler:
the timeline that sent the signal is running.

What needs to be checked in the signal handler is if there are any
timelines running other than the one that emitted the ::started signal,
which we know is running anyway.

This prevents frames from being lost at the beginning of an animation when
a timeline is started after a quiescent period.

cbbc1a9ca3 [build] Copy cogl-enum-types.h under the guard
We avoid rebuilding cogl-enum-types.h and cogl-enum-types.c by
using a "guard" -- a stamp file that will block Makefile. Since
we need cogl-enum-types.h into /clutter/cogl as well for the
cogl.h include to work, if we copy the cogl-enum-types.h
unconditionally it will cause a rebuild of the whole COGL; which
will cause a full rebuild.

To solve this, we can copy the header file when generating it
under the stamp file.

e565c1f1db [build] Encode the target into the backend library
The libclutter-cogl internal object should be the only dependency
for Clutter, since we are already copying it inside clutter/cogl
for the introspection scanner. For this reason, the backend-specific,
real internal object should be built with the backend encoded into
the file name, like libclutter-common. This makes the build output
a little bit more clear: instead of having two:

  LINK libclutter-cogl-common.la
  ...
  LINK libclutter-cogl.la
  LINK libclutter-cogl.la

We'll have:

  LINK libclutter-cogl-common.la
  ...
  LINK libclutter-cogl-gl.la
  LINK libclutter-cogl.la

Same applies for the GLES backend.

f0849fc3e2 [cogl journal] If we are only flushing one quad use a TRIANGLE_FAN
At the moment Cogl doesn't do much batching of quads so most of the time we
are flushing a single quad at a time.  This patch simplifies how we submit
those quads to OpenGL by using glDrawArrays with GL_TRIANGLE_FAN mode
instead of sending indexed vertices using GL_TRIANGLES mode.

Note: I hope to follow up soon with changes that improve our batching and
also move the indices into a VBO so they don't need to be re-validated every
time we call glDrawElements.

cogl_create_context is dealt with internally when _cogl_get_default context

It might be nicer later to get an object back when creating a context so
Cogl can support multiple contexts, so these functions are being removed
from the API until we get a chance to address context management properly.

For now cogl_destroy_context is still exported as _cogl_destroy_context so
Clutter could at least install a library deinit handler to call it.
