Two of the meta texture constructors which take a flags parameter were
ignoring the COGL_TEXTURE_NO_AUTO_MIPMAP flag when creating an
underlying CoglTexture2D. These have now been fixed to call
cogl_primitive_texture_set_auto_mipmap after constructing the texture.

This adds public constructors which take a CoglBitmap to all primitive
texture types. This constructor should be considered the canonical
constructor for initializing the texture with data because it should
be possible to wrap any type of data in a CoglBitmap. Having at least
this single constructor avoids the need to have an explosion of
constructors such as new_from_data, new_from_pixel_buffer and
new_from_file etc.
The already available internal bitmap constructor for CoglTexture2D
has had its flags parameter removed under the assumption that flags do
not make sense for primitive textures. The meta constructor
cogl_texture_new_from_bitmap now just explicitly calls set_auto_mipmap
after constructing the texture depending on the value of the
COGL_TEXTURE_NO_AUTO_MIPMAP flag.

This interface represents any textures that are backed by a single
texture in GL and that can be used directly with the
cogl_framebuffer_draw_attributes family of functions. This currently
equates to CoglTexture2D, CoglTexture3D and CoglTextureRectangle.
The interface currently has only one method called
cogl_primitive_set_auto_mipmap. This replaces the
COGL_TEXTURE_NO_AUTO_MIPMAP flag from the CoglTextureFlags parameter
in the constructors. None of the other flags in CoglTextureFlags make
sense for primitive textures so it doesn't seem like a good idea to
need them for primitive constructors.
There is a boolean in the vtable to mark whether a texture type is
primitive which the new cogl_is_primitive function uses. There is also
a new texture virtual called set_auto_mipmap which is only required to
be implemented for primitive textures.

This adds a context member to CoglBitmap which stores the context it
was created with. That way it can be used in texture constructors
which use a bitmap. There is also an internal private function to get
the context out of the bitmap which all of the texture constructors
now use. _cogl_texture_3d_new_from_bitmap has had its context
parameter removed so that it more closely matches the other bitmap
constructors.

The previous code to initialise the depth state on the default
pipeline wasn't initialising the magic number. If you later tried to
retrieve the depth state using cogl_pipeline_get_depth_state you would
end up with an invalid depth state struct and you would just get
warnings if you tried to use it for anything. This patch just replaces
the initialisation with a call to cogl_depth_state_init because it
uses the same values anyway.

get_texture_bits_via_offscreen does not check the return value of
cogl_framebuffer_read_pixels_into_bitmap which results into never
using the fallback path texture_get_cb.
cogl_framebuffer_read_pixels_into_bitmap does not check whether the framebuffer
is properly allocated though; so fix that as well.

We were using g_list_foreach() prior to the first Apocalypse, and that
function is resilient against changes to the list while iterating it;
since we are not using a GList any more, we need handle this case
ourselves.
This also avoids the warning
Cogl-WARNING **: ./cogl-buffer.c:215: GL error (1285): Out of memory
generated by cogl_buffer_map when the CoglBuffer has zero length.
When the easing state has a duration of zero milliseconds we can skip
the entire create_transition() call inside set_width() and set_height(),
to avoid what may be a costly call to get_preferred_*.
If we update a transition that is currently playing, we need to check
the current easing state, and look at the eventual duration, in case
the user wants to cancel the transition.
Instead of checking the duration of the current easing state we should
check if there's a transition in progress, and update it
unconditionally.
If there is no easing state, or the easing state has a duration of zero
milliseconds, then create_transition() should bail out early and set the
requested final state.
This allows us to write:
clutter_actor_save_easing_state (actor);
clutter_actor_set_x (actor, 200);
clutter_actor_restore_easing_state (actor);
[...]
clutter_actor_set_x (actor, 100);
and have the second set_x() update the easing in progress, instead of
being ignored.

Commit 80626e75842a24c3d0a45068e241ba309f6ec138 removed an
IN_DESTRUCTION check from within the add_child_internal() method,
outlining an option for bringing it back. It was too late for the 1.10
cycle to do it, and eventually pick up the pieces, but now that we're
at the beginning of the 1.11 cycle we can restore it, and add checks
elsewhere to balance it.
This patch fixes clutter to not crash when multiple animations share
the same timeline and the actors are explicitly destroyed before
the timeline completes (bug 672890)
When mutter recognizes a full-screen window, it tries to raise it to the top
of the stack. Unfortunately, a recent rewrite of the stack code didn't do
well with raising a window to the top of the stack if the stack wasn't in
a consistent state -- it would crash. Ensure that the stack is in a consistent
state at the top of meta_stack_raise/meta_stack_lower.
