8ded6663fb [material] fix _set_alpha_test_function: missing a glEnable(GL_ALPHA_TEST)
Since the default alpha test function of GL_ALWAYS is equivalent to
GL_ALPHA_TEST being disabled we don't need to worry about Enabling/Disabling
it when flushing material state, instead it's enough to leave it always
enabled.  We will assume that any driver worth its salt wont incur any
additional cost for glEnable (GL_ALPHA_TEST) + GL_ALWAYS vs
glDisable (GL_ALPHA_TEST).

This patch simply calls glEnable (GL_ALPHA_TEST) in cogl_create_context

3f64f57830 [texture] remove redundant if (paint_opacity == 0) bailout
clutter_texture_paint shouldn't need to optimize the case where
paint_opacity == 0 and bailout, since we've been doing this optimization for
all actors in clutter_actor_paint for a while now.

aa53dccfce cogl-vertex-buffer: Don't disable any texture coord arrays
The enabled state of the texture coord arrays is cached in the cogl
context so there is no need to disable them when we've finished
rendering a vbo.

401892af11 cogl: Record new enabled arrays in _cogl_disable_other_texcoord_arrays
When _cogl_disable_other_texcoord_arrays is called it disables the
neccessary texcoord arrays and then removes the bits for the disabled
arrays in ctx->texcoord_arrays_enabled. However none of the places
that call the function then set any bits in ctx->texcoord_arrays_enabled
so the arrays would never get marked and they would never get disabled
again.

This patch just changes it so that _cogl_disable_other_texcoord_arrays
also sets the corresponding bits in ctx->texcoord_arrays_enabled.

b77c0c91d7 drag-action: Re-use press_button in emit_drag_end()
Since emit_drag_end() can be called from a MOTION event capture we
cannot call clutter_event_get_button(). We should, instead, use the
press_button value because if we're emitting ::drag-end it means we
also emitted ::drag-begin and the value is valid.

380e7b8b5d cogl: Use a CoglBitmask to store the list of used texcoord arrays
Instead of directly using a guint32 to store a bitmask for each used
texcoord array, it now stores them in a CoglBitmask. This removes the
limitation of 32 layers (although there are still other places in Cogl
that imply this restriction). To disable texcoord arrays code should
call _cogl_disable_other_texcoord_arrays which takes a bitmask of
texcoord arrays that should not be disabled. There are two extra
bitmasks stored in the CoglContext which are used temporarily for this
function to avoid allocating a new bitmask each time.

218efd0b62 cogl: Add an internal CoglBitmask type
This implements a growable array of bits called CoglBitmask. The
CoglBitmask is intended to be cheap if less than 32 bits are used. If
more bits are required it will allocate a GArray. The type is meant to
be allocated on the stack but because it can require additional
resources it also has a destroy function.

889dcee384 cogl-material: Fix the count of the number of layers
Previously the counter for the number of layers was only updated
whenever the texture handle for a layer changes. However there are
many other ways for a new layer to be created for example by setting a
layer combine constant. Also by default the texture on a layer is
COGL_INVALID_HANDLE so if the application tries to create an explicit
layer with no texture by calling cogl_material_set_layer with
COGL_INVALID_HANDLE then it also wouldn't update the count.

This patch fixes that by incrementing the count in
cogl_material_get_layer instead. This function is called by all
functions that may end up creating a layer so it seems like the most
appropriate place.

ae0354e9ba cogl-vertex-buffer: Don't disable layers with no texture coords
It should be quite acceptable to use a texture without defining any
texture coords. For example a shader may be in use that is doing
texture lookups without referencing the texture coordinates. Also it
should be possible to replace the vertex colors using a texture layer
without a texture but with a constant layer color.

enable_state_for_drawing_buffer no longer sets any disabled layers in
the overrides. Instead of counting the number of units with texture
coordinates it now keeps them in a mask. This means there can now be
gaps in the list of enabled texture coordinate arrays. To cope with
this, the Cogl context now also stores a mask to track the enabled
arrays. Instead of code manually iterating each enabled array to
disable them, there is now an internal function called
_cogl_disable_texcoord_arrays which disables a given mask.

I think this could also fix potential bugs when a vertex buffer has
gaps in the texture coordinate attributes that it provides. For
example if the vertex buffer only had texture coordinates for layer 2
then the disabling code would not disable the coordinates for layers 0
and 1 even though they are not used. This could cause a crash if the
previous data for those arrays is no longer valid.

ff7ce2c5b2 test-cogl-materials: Run the 'all layers' test with different prims
The drawing code from test_invalid_texture_layers which draws a
rectangle, a polygon and a vertex buffer has been split out to
separate function. test_using_all_layers now also uses this so that it
will also test the other two primitives. This causes the test to fail
when all of the layers are drawn using a vertex buffer.

6a313ec2e2 Implemented clutter_actor_get_accessible
Added the implementation for clutter_actor_get_accessible, virtual
ClutterActor function, used to obtain the accessible object of
any ClutterActor.

As it is defined virtual, it would be possible to redefine it, so
any custom clutter actor could implement their accessibility object,
withouth relying totally on a accessibility implementation module.

See gtkiconview as example.

af84d97fca interval: Add a pointer variant to compute_value()
ClutterInterval.compute_value() computes the new value given a progress
and copies it to a given GValue. Since most of the time we want to pass
that very same value to another function that copies it again, we should
have a compute_value() variant that stores that computed value inside
ClutterInterval and returns a pointer to it. This way we initialize the
result GValue just once and we never copy it, as long as the Interval
instance is valid.
