tex->first_pixels was never set for foreign textures, leading
to a crash when the texture object is freed.
As a quick fix, simply set to NULL. A more complete fix would
require remembering if we had ever seen the first pixel uploaded,
and if not, doing a glReadPixel to get it before triggering the
mipmap update.

It's very common that there's no reasonable fallback to do if the
blend or combine string you set isn't supported. So, rather than
requiring everybody to pass in a GError purely to catch syntax erorrs,
automatically g_warning() if a parse error is encountered and @error
is NULL.

When we complete a timeline, we clamp the elapsed_time variable
to the range of the timeline. We need to adjust msecs_delta so that
when we check for hit markers we have the correct interval.

The Animation should be referenced during the notification of the
alpha value, since the callback is invoked depending on the Alpha
and it won't vivify the Animation instance for us.

ClutterEvent is not really gobject-introspection friendly because
of the whole discriminated union thing. In particular, if you get
a ClutterEvent in a signal handler, you probably can't access the
event-type-specific fields, and you probably can't call methods
like clutter_key_event_symbol() either, because you can't cast the
ClutterEvent to a ClutterKeyEvent.
The cleanest solution is to turn every accessor into ClutterEvent
methods, accepting a ClutterEvent* and internally checking the event
type.

According to clutter_texture_set_cogl_texture you should unref the handle as

Setting the pixmap for an unrealized ClutterGLXTexturePixmap should
not cause it to be realized, and certainly shouldn't cause the the
REALIZED flag to be set without using clutter_actor_realize().
This patch uses the simple approach that;
- pixmap changes on an unrealized ClutterGLXTexturePixmap
are ignored
- when the ClutterGLXTexturePixmap is realized, we then create
the GLXPixmap and the corresponding texture.
The call to clutter_glx_texture_pixmap_update_area() is moved
from create_cogl_texture() to
clutter_glx_texture_pixmap_create_glx_pixmap() since
create_cogl_texture() is only called from one place, and updating
the area is really something we do *after* creating the texture,
not part of creating the texture.
clutter_glx_texture_pixmap_create_glx_pixmap() is reorganized a
bit to avoid debug-logging confusingly if it's called before a pixmap
has been set, and for readability.

An implementaton of realize() never needs to set the
CLUTTER_ACTOR_REALIZED flag, though it can unset the flag if
things fail unexpectedly. (Previously, stage backend implementations
had to do this since clutter_actor_realize() wasn't used; this
is no longer the case.)

Due to the accumulation of floating point errors, natural_width
and min_width can diverge significantly even if the math for
computing them is correct. So just clamp natural_width to
min_width instead of warning about it.

If we use float temporaries when computing the bounds of
a group, then, depending on what variables are kept in registers
and what stored on the stack, the accumulated difference between
natural_width and min_width can be more than FLOAT_EPSILON.
Using double temporaries will eliminate the difference in most
cases, or, very rarely, reduce it to a last-bit error.

If we are cloning an source actor with an unmapped parent, then when
we temporarily map the source actor:
- We need to skip the check that a mapped actor has a mapped
parent.
- We need to realize the actor's parents before mapping it,
or we'll get an assertion failure in clutter_actor_update_map_state()
because an actor with an unmapped parent is !may_be_realized.

Setting the stage size using clutter_actor_set_size() is almost always
wrong: the X11 stage implementation should save the size and queue a
relayout -- like it does when receiving a ConfigureNotify. The same
should happen when setting it to be full screen.
Since we build the Cogl GIR inside /clutter/cogl we should be looking
there when building the Clutter GIR. Otherwise g-ir-scanner will look
inside the gir directory -- and if you never built Clutter before it
will error out.

The test was quiting after the 2nd frame but it should be the third frame because
the test doesn't actually check results until the third frame due to the workaround
for drivers with broken glReadPixels.
(When first written the test would have been verified with the
clutter_main_quit() commented out which gives visual feedback of what the
test does, so the off by one would have snuck in just before uncommenting
and pushing.)
The load-finished signal has a GError* argument which is meant to
signify whether the loading was successful. However many of the
places in ClutterTexture that emit this signal directly pass their
'error' variable which is a GError** and will be NULL or not
completely independently of whether there was an error. If the
argument was dereferenced it would probably crash.
The test-texture-async interactive test case should also verify
that the ::load-finished signal is correctly emitted.

It seems GNU Gold (the new linker) either behaves as if with
--no-undefined by default, or has some issue preventing it from not
doing that when instructed to (I'm not sure if this actually
happens). In any case, clutter uses the Xshm extensions, but does not
link to libXext, which makes gold unhappy.

It should be possible render a single PangoLayout with different
colors without recalculating the layout. This was not working because
the color used at the first edit was being stored in the display
list. This broke changing the opacity on a ClutterText.
Now each node in the display list has a 'color override' flag which
marks whether it should use the base color or not. The base color is
now passed in from _cogl_pango_display_list_render_texture. The alpha
value is always taken from the base color.
The clutter_redraw() function is used by libraries embedding
Clutter inside another toolkit, instead of queueing a redraw
on the embedded stage. This means that clutter_redraw() should
perform the same sequence of actions done by the redraw idle
callback.
Clutter short-circuits painting when an actor's opacity is
zero. However if the actor is being painted from a ClutterClone then
it will be painted using the clone's opacity instead so the test was
broken.
A merge conflict gone bad: the IMAGE_PC_FILES variable was not appended
to the CLUTTER_REQUIRES one, thus leading to Clutter depending on
GdkPixbuf but never actually checking for it.

The XInput support in Clutter is still using XI 1.x. This will never
work correctly, and we are all waiting for XInput 2 anyway. The changes
internally should be minimal, so we can leave everything in place, but
it's better to disable XInput support by default -- at least for the
time being.
The texture filters are now a property of the material layer rather
than the texture object. Whenever a texture is painted with a material
it sets the filters on all of the GL textures in the Cogl texture. The
filter is cached so that it won't be changed unnecessarily.
The automatic mipmap generation has changed so that the mipmaps are
only generated when the texture is painted instead of every time the
data changes. Changing the texture sets a flag to mark that the
mipmaps are dirty. This works better if the FBO extension is available
because we can use glGenerateMipmap. If the extension is not available
it will temporarily enable automatic mipmap generation and reupload
the first pixel of each slice. This requires tracking the data for the
first pixel.
The COGL_TEXTURE_AUTO_MIPMAP flag has been replaced with
COGL_TEXTURE_NO_AUTO_MIPMAP so that it will default to
auto-mipmapping. The mipmap generation is now effectively free if you
are not using a mipmap filter mode so you would only want to disable
it if you had some special reason to generate your own mipmaps.
ClutterTexture no longer has to store its own copy of the filter
mode. Instead it stores it in the material and the property is
directly set and read from that. This fixes problems with the filters
getting out of sync when a cogl handle is set on the texture
directly. It also avoids the mess of having to rerealize the texture
if the filter quality changes to HIGH because Cogl will take of
generating the mipmaps if needed.
The mapping and unmapping of the X11 stage implementation is
a bit bong. It's asynchronous, for starters, when it really
can avoid it by tracking the state internally.
The ordering of the map/unmap sequence is also broken with
respect to the resizing.
By tracking the state internally into StageX11 we can safely
remove the MapNotify and UnmapNotify X event handling.
In theory, we should use _NET_WM_STATE a lot more, and reuse
the X11 state flags for fullscreening as well.
Apparently, the XInput extension is using the same pkg-config
file ('xi') for both the 1.x and the 2.x API, so we need to
check for both the 1.x XGetExtensionVersion and the 2.x
XQueryInputVersion.
