Attached patch contains a cookbook recipe about key press event
handling.
It covers both a simple approach (connecting a callback to a
key-press-event signal which manually analyses the key and
modifiers), and a more complicated one based on a binding pool.
There's also some discussion of the two approaches.

The cookbook contains a commented-out recipe covering scaling images
inside a texture while retaining their aspect ratio; the attached
patch fleshes out this recipe.

A typo in clutter-event.c meant that the wrong struct location could be
used for the input device of key events. Also, a typo in the X11 event
code meant that key-presses would come from the pointer device (releases
would still come from the keyboard device).
Allow using the BindConstraint to bind width and height of a source
actor.
Also, add a test for the BindConstraint showing all types of usages
for this constraint class.
Some of the arguments to the material and path functions were taking a
pointer to a CoglColor or an array of floats that was not intended to
be written to but were not marked with const.
Update the documentation of :font-name, to make it clear that by setting
it to NULL the Text actor will use the default font.
Also, set the annotation for the @font_name argument of the setter to be
allow-none, and allow passing NULL through bindings.
If a ClutterText actor is using the default font from the backend then
we should track font name changes and update it accordingly. This only
applies to ClutterText actors with the :font-name property unset or
explicitly set to NULL.
It's possible that a single WM_MOUSEWHEEL event can arrive with a
scroll amount greater than WHEEL_DELTA. Previously it would accumulate
these amounts but it would still only emit a single event per
message. For example, if a message arrived that is worth two
WHEEL_DELTAs then it would emit one event and leave scroll_pos as
+WHEEL_DELTA. If the wheel is then scrolled in the opposite direction
then wheel delta would end up as zero and the scroll event would get
lost.
This patch fixes it so that it always emits enough events to put
scroll_pos back to less than WHEEL_DELTA.

Previously the window procedure for the stage window would always
create a ClutterEvent struct for every message and then pass that on
to message_translate to fill in the details. message_translate could
return FALSE to abandon the event. Instead of this, message_translate
now creates and queues the event itself whenever it sees a message
that could translate to an event. The function now returns void. This
has a number of advantages:
* It saves redundantly allocating events for messages that Clutter
doesn't care about.
* A single message can now easily be translated into multiple events.
* There were some messages that were handled and did not fill in the
event struct but did not cause the function to return FALSE. I think
this would end up with a CLUTTER_NOTHING event being emitted.

The -rdynamic linker option is specific to ELF so it was breaking
builds on systems with other object formats such as Windows and
Solaris. This patch replaces that option with -export-dynamic which is
a portable libtool option which should do the right thing on each
platform.

in _cogl_material_prune_empty_layer_difference we sometimes unref the
given layer before dereferencing it to get a pointer to its parent. This
defers the unref until after we have fetched the parent pointer.
Commit 7fae8ac051 changed cogl-defines.h.in so there is only a
single copy in clutter/cogl/ instead of one for each driver. However
the old files were still mentioned in the EXTRA_DIST of the
Makefile.am so make distcheck was failing.

A pedantic change to get_fbconfig_for_depth() so that we don't need to
make any assumptions about the GLXFBConfig typedef or what values
we can overload to indicate an invalid config.
get_fbconfig_for_depth() now simply returns FALSE if it fails to find a
config.
While dragging we don't need to perform picking to determine the actor
underneath the pointer, for two reasons:
• we use a capture on the stage to determine the motion delta.
• we know the actor underneath the pointer because that's the
actor we are dragging around.
This change should make dragging actors in complex scenes a bit faster.
The -Bsymbolic-functions linker flag allows to avoid intra-library
PLT jumps on ELF platforms. It is similar to the aliasing hack in
GLib and GTK+, but definitely less messy.
The configure script should look for the flags, in order to support
platforms/linkers that do not have it.
The pixmap handling of both of the texture pixmap actors in Clutter is
now removed and instead it just creates a CoglTexturePixmapX11. Both
actors are now equivalent so there is no need to choose between the
two.
This is a publicly exposed texture backend to create a texture which
contains the contents of an X11 pixmap. The API is currently marked as
experimental.
The backend internally holds a handle to another texture. All of the
backend virtuals simply redirect to the internal texture.
The texture can optionally be automatically updated if the
automatic_updates parameter is TRUE. If set then Cogl will listen for
damage events on the pixmap and update the texture accordingly.
Alternatively a damage object can be created externally and passed
down to Cogl.
The updates can be performed with XGetImage, XShmGetImage or the
GLX_EXT_texture_pixmap extension. If the TFP extension is used it will
optionally try to create a rectangle texture if the driver does not
support NPOTs or it is forced through the
COGL_PIXMAP_TEXTURE_RECTANGLE or CLUTTER_PIXMAP_TEXTURE_RECTANGLE
environment variables.
If the GLXFBConfig does not support mipmapping then it will fallback
to using X{Shm,}GetImage. It keeps a separate texture around for this
so that it can later start using the TFP texture again if the texture
is later drawn with mipmaps disabled.
