4355621aeb group: make it comparable to ClutterBox
There is a lot of duplication between ClutterGroup and ClutterBox so
this makes the two files diff-able so that new fixes can easily be
ported to both and bug fixes missing in one or the other can be spotted
more easily. This doesn't change the behaviour of either actor; it's
really just a shuffle around of code and normalizes the coding style to
make the files comparable.

This has already uncovered one bug in ClutterBox, and also highlights
a bug in ClutterGroup + many other actors:

1) ClutterGroup::real_foreach was recently changed to use
   g_list_foreach instead of manually iterating the child list so it can
   safely handle calls like:
     clutter_container_foreach (container, clutter_actor_destroy);
   ClutterBox is still manually iterating the list.

2) In ClutterGroup we guard _queue_redraw() calls like this:
    if (CLUTTER_ACTOR_IS_VISIBLE (container))
	clutter_actor_queue_redraw (CLUTTER_ACTOR (container));
   In ClutterBox we don't:
     I think ClutterBox is correct here because
     clutter_actor_queue_redraw already optimizes the case where the
     actor's not visible, but it also considers that the actor may be
     cloned and so the guard in ClutterGroup could break clones. This
     actually highlights a wider clutter bug since the same kinds of
     guards can be found in all other clutter actors.

44818a4827 cogl: Add a fallback for when the signbit macro is missing
The signbit macro is defined in C99 so it should be available but some
versions of GCC don't appear to define it by default. If it's not
available we can use a hack to test the bit directly.

1899dbdc27 backend-glx: Fix glXQueryVersion test
This fixes some backwards logic for asserting that we have a GLX major
version == 1 and a minor version >= 2. (NB: Although we technically
depend on GLX 1.3 features, we still have to support drivers that report
GLX 1.2 because there are a lot of mesa drivers out there incorrectly
report GLX 1.2 even though they export extensions that depend on GLX
1.3)

ce1bb3d858 cogl-material: Layers are not equal if the filters aren't equal
A material layer can not be considered equal if it is using different
texture filtering modes. This was causing problems where rectangles

5d702853b8 glx backend: Adds support for GLX_INTEL_swap_event
If your OpenGL driver supports GLX_INTEL_swap_event that means when
glXSwapBuffers is called it returns immediatly and an XEvent is sent when
the actual swap has finished.

Clutter can use the events that notify swap completion as a means to
throttle rendering in the master clock without blocking the CPU and so it
should help improve the performance of CPU bound applications.

f5d2f58b03 docs: Clean up the unused symbols for Cogl
Gtk-doc is reporting a lot of false positives in the unused text file,
mostly because of new private files that have been added to Cogl but not
to the gtk-doc ignore list for the Cogl API reference.

Once the false positives have been removed we have a couple of really
missing symbols that should be added to the cogl-sections.txt file.

e46db37c03 conform: fix stack corruption in test-behaviours.c
The test was calling g_object_get to fetch the "opacity-start" property

given that the getter function returns guint8 values so this also adds a
comment explaining what's going on.

a02253f19a cogl-texture-2d: Use _cogl_texture_driver_gen to generate the GL tex
_cogl_texture_driver_gen is needed to set the texture minification
mode to Cogl's default of GL_LINEAR. There was also a line to set this
in _cogl_texture_2d_new_with_size but it wasn't working because it was
called *before* the texture was bound. If the texture was later
rendered with the default material it then it would end up with GL's
default mipmap filtering mode but without mipmaps so it would render
white squares instead.

1b2ff7eff7 cogl: Use SSE2 when possible for premultiplying
This adds a fast path for premultiplying an RGBA image using SSE2
instructions. SSE registers are 128-bit and we need at least 16-bits
per component for the intermediate result of the multiplication so we
can do two pixels in parallel with one register. The function
interleaves 2 SSE registers to multiply 4 pixels in one function call
with the hope that this will pipeline better.

d0fe479536 cogl-pixel-buffer: Add a fallback path
First, let's add a new public feature called, surprisingly,
COGL_FEATURE_PBOS to check the availability of PBOs and provide a
fallback path when running on older GL implementations or on OpenGL ES

In case the underlying OpenGL implementation does not provide PBOs, we
need a fallback path (a malloc'ed buffer). The CoglPixelBufer
constructors will instanciate a subclass of CoglBuffer that handles
map/unmap and set_data() with a malloc'ed buffer.

The public feature is useful to check before using set_data() on a
buffer as it will mean doing a memcpy() when not supporting PBOs (in
that case, it's better to create the texture directly instead of using a
CoglBuffer).

abbb668163 cogl-pixel-buffer: add a pixel buffer object class
This subclass of CoglBuffer aims at wrapping PBOs or other system
surfaces like DRM buffer objects. Two constructors are available:

cogl_pixel_buffer_new() with a size when you only care about the size of
the buffer (such a buffer can be used to store several texture data such
as the three planes of a I420 frame).

cogl_pixel_buffer_new_full() is more a 1:1 mapping between the data and
an underlying surface, with the possibility of having access to a low
level memory buffer that may have a stride.

b5e9710cdf cogl-buffer: add an abstract class around openGL's buffer objects
Buffer objects are cool! This abstracts the buffer API first introduced
by GL_ARB_vertex_buffer_object and then extended to other objects.

The coglBuffer abstract class is intended to be the base class of all
the buffer objects, letting the user map() buffers. If the underlying
implementation does not support buffer objects (or only support VBO but
not FBO for instance), fallback paths should be provided.

de8a6314f1 cogl: new textures sould have GL_TEXTURE_MIN_FILTER set to GL_LINEAR
The only way the user has to set the mipmap filters is through the
material/layer API. This API defaults to GL_LINEAR/GL_LINEAR for the max
and min filters. With the main use case of cogl being 2D interfaces, it
makes sense do default to GL_LINEAR for the min filter.

When creating new textures, we did not set any filter on them, using
OpenGL defaults': GL_NEAREST_MIPMAP_LINEAR for the min filter and
GL_LINEAR for the max filter. This will make the driver allocate memory
for the mipmap tree, memory that will not be used in the nominal case
(as the material API defaults to GL_LINEAR).

This patch tries to ensure that the min filter is set to GL_LINEAR
before any glTexImage*() call is done on the texture by setting the
filter when generating new OpenGL handles.
