3c073d82c7 [cogl] Provide GTypes for COGL types
COGL types should be registered inside the GType system, for
bindings and type checking inside properties and signals.

CoglHandle is a boxed type with a ref+unref semantics; slightly evil
from a bindings perspective (we cannot associate custom data to it),
but better than nothing.

The rest of the exposed types are enumerations or bitmasks.

63ae25972e [cogl] Add cogl_is_material to cogl-material.h
The COGL_DEFINE_HANDLE macro generates a cogl_is_<type> function
as well, to check whether a CoglHandle opaque pointer is of type
<type>.

The handle for CoglMaterial does not export cogl_is_material() in
its installed header.

a86b9834d3 [ClutterBehaviourRotate] Fix up some breakage from the cogl-float branch merge
The rotation angle calculated in clutter_behaviour_rotate_alpha_notify
gets applied to each actor using clutter_behaviour_actors_foreach. The
angle is a ClutterFixed value. Before the cogl float branch merge it
was stuffed into a gpointer using GPOINTER_TO_UINT. The pointer was
then converted back to a uint and cast to a ClutterFixed which worked
out fine even for negative numbers.

After the cogl-float merge the angle is effectively a gfloat. This
gets cast to a uint and stored in a pointer and converted back to a
float via a uint at the other end. However this fails for negative
numbers because a uint -> float conversion can't take advantage of
overflow to preserve the sign so you end up with a large number.

It also had the side effect that it only rotated in whole degrees.

This commit fixes the problem by just passing the ClutterFixed value
inside a closure struct instead of trying to stuff it into a pointer.

deed85035f Allow rotation angle properties to be negative
Bug 1167 - clutter_effect_rotate improperly clamps negative angles

The rotation angle properties had a minimum value of 0.0 but the
rotation works fine with a negative value so the limitation is
unnecessary. This makes rotation using the ClutterAnimation API more
flexible because it was previously not possible to rotate
counter-clockwise from the 0.0 position.

99248fa90f Override the opacity when painting a clone instead of combining
When rendering a clone before this commit the clone's opacity was
combined with the opacity of the source but this is not usually the
desired effect. Instead the clone's opacity (combined with its
parents) should completely override the opacity of the source.

03018f0c2a [Cogl] Renames cogl_paint_init to cogl_clear and adds a cogl_disable_fog function
cogl_paint_init was a bit too miscellaneous; it mainly cleared the color, depth
and stencil buffers but arbitrarily it also disabled fogging and lighting.

It no longer disables lighting, since we know Cogl never enables lighting and
disabling of fog is now handled with a seperate function.

Since I noticed cogl_set_fog was taking a density argument documented as
"Ignored" I've also added a mode argument to cogl_set_fog which exposes the
exponential fog modes which can make use of the density.

57ffcdf014 Added a mutex for clutter asynchronous textures threads.
Bug #1453 - Asynchronous texture loading can starve cpu.

Add a mutex that is held in the loader threads during the image
decoding. We were spawning and starting a thread for each asynchronously
loaded texture. This can cause cpu / memory starvation when many pixbuf
loaders allocate their temporary memory at the same time.

Also added -fno-strict-aliasing to MAINTAINER_CFLAGS in configure.ac
to avoid incorrect warnings caused by the static mutex code.

2fe0228f92 [x11] Add backend-specific get_current_event_time()
The clutter_get_current_event_time() function will return the event
timestamp coming from a Clutter event. Clutter might synthesize or
throttle events, so the function cannot be used when dealing with
backend-specific use cases.

The X11 backend is the only backend supported by Clutter that makes
use of timestamps, so it's altogether fitting that it should come
with a specific function to deal with the timestamps of the X events.

747233a8ac [clutter-main] Fix the input device passed to set_motion_last_actor
In generate_enter_leave_events it passes the device pointer from the
event to set_motion_last_actor but it was reading it directly from
event->motion.device. However the function is also used to process
button events so it would read from the wrong location in this case.

The device location in the union happened to be in the same place as
the click_count field of ClutterButtonEvent so it only mattered if the
click_count is non-zero. The X11 backend doesn't set this but
Clutter-GTK does so it was causing a crash.

1fcddb3b10 [win32] Track mouse leave messages
Bug 1178 - No enter / leave events on actors when pointer leaves the
           stage window

This patch causes the Win32 backend to emit CLUTTER_LEAVE events when
a WM_MOUSELEAVE event is received in the same way that f505536 does
for the X11 backend.

Windows will only send WM_MOUSELEAVE events if they are previously
requested using TrackMouseEvent so this needs to be called whenever
the mouse enters the window. There is no WM_MOUSELEAVE event but we
can detect when the mouse enters because we get a WM_MOUSEMOVE event.

5d6a11e1bf Emit CLUTTER_LEAVE events when the pointer leaves the stage
Bug 1178 - No enter / leave events on actors when pointer leaves the
           stage window

The patch is mostly thanks to Johan Bilien with small modifications
based on suggestions by Owen Taylor.

The X11 backend now listens for enter and leave notifications. Leave
notifications get translated directly to a CLUTTER_LEAVE
event. Clutter can detect these special events because the source
actor is NULL in which case it sets the source actor to the last known
actor and then sets the last known actor to NULL.

Enter notifications just get translated to CLUTTER_MOTION events which
will cause Clutter to generate an enter event through the usual code
path.

0ac6d6637e [list-model] Make ClutterListModel subclassable
ClutterListModel has been added as a terminal class in case we
decided to change API or implementation.

Apparently, it's a lot more resilient than we expected -- or far
too few are using it and reporting bugs. Once common issue, though,
is that it cannot be subclassed, hence it's fairly limited in its
usage.

In the hope that more developers will start using it, here's a
patch that makes ListModel a fully subclassable object.

May whatever god you believe in have mercy on your eventual soul.

29bff6890a [texture] Consolidate the quality to filter conversions
To convert from a TextureQuality to a COGL filter enumeration
we need to perform two function calls. Since we need both filters
when calling cogl_texture_set_filters() we can safely consolidate
the two conversion functions into one. This also allows using a
shorter function name, thus reducing the lenght of the lines
involved and, more importantly preventing Emmanuele from crying.

6bc7f4c723 [actor] Force a relayout on set_parent()
The current code that handles the invariant that the new parent
of an actor needing a layout should also be queued for relayout
is hitting the short-circuiting we do in the queue_relayout()
method.

In order to fix this we can forcibly set the actor to need a
width/height request and an allocation; then we queue a relayout
on the parent.

9cf02bfdb9 [text] Rename :alignment to :line-alignment
The :alignment property is prone to generate confusion: developers
will set it thinking that the contents of a ClutterText will
automagically align themselves.

Instead of using the generic term :alignment, and following the
GTK+ convention, we should use a more specific term, conveying the
actual effect of the property: alignment of the lines with respect
to each other, and not to the overall allocated area.

49359407b0 [cogl-texture] Fix the count for the number of enabled arrays
The quad drawing code keeps track of the number of texture units that
have the tex coord array enabled so that in the next call it can
disabled any that are no longer enabled. However it was using 'i+1' as
the count but 'i' is already set to 'n_layers' from the previous for
loop.

Therefore it was disabling an extra texture unit. This doesn't
normally matter but it was causing GLES 2 to pointlessly realize an
extra unit.

e88de5f5fd Fix building GLES 2 after the material branch merge
- In cogl-material.h it directly sets the values of the
  CoglMaterialLayerCombineFunc to some GL_* constants. However these
  aren't defined in GLES 2 beacuse it has no fixed function texture
  combining. Instead the CGL_* versions are now used. cogl-defines.h
  now sets these to either the GL_* version if it is available,
  otherwise it directly uses the number.

- Under GLES 2 cogl-material.c needs to access the CoglTexture struct
  so it needs to include cogl-texture-private.h

- There are now #define's in cogl-gles2-wrapper.h to remap the GL
  function names to the wrapper names. These are disabled in
  cogl-gles2-wrapper.c by defining COGL_GLES2_WRAPPER_NO_REMAP.

- Added missing wrappers for glLoadMatrixf and glMaterialfv.

- Renamed the TexEnvf wrapper to TexEnvi because the latter is used
  instead from the material API.

edbe9a0377 [cogl-material] Always bind the new texture handle
Cogl previously tried to cache the currently bound texture when
drawing through the material API to avoid excessive GL calls. However,
a few other places in Cogl and Clutter rebind the texture as well so
this can cause problems.

This was causing shaped windows to fail in Mutter because
ClutterGLXTexturePixmap was binding a different texture to update it
while the second texture unit was still active which meant the mask
texture would not be selected when the shaped window was drawn
subsequent times.

Ideally we would fix this by providing a wrapper around glBindTexture
which would affect the cached value. The cache would also have to be
cleared if a selected texture was deleted.
