278daca61c cairo-texture: Deprecate create()/create_region()
The recommended way of drawing on a ClutterCairoTexture is the ::draw
signal.

2f445682b1 cairo-texture: Use signal-based drawing
The current "create context/draw/destroy context" pattern presents
various problems. The first issue is that it defers memory management to
the caller of the create() or create_region() methods, which makes
bookkeeping of the cairo_t* harder for language bindings and third party
libraries. The second issue is that, while it's easier for
draw-and-forget texturs, this API is needlessly complicated for contents
that have to change programmatically - and it introduces constraints
like calling the drawing code explicitly after a surface resize (e.g.
inside an allocate() implementation).

By using a signal-based approach we can make the CairoTexture actor
behave like other actors, and like other libraries using Cairo as their
2D drawing API.

The semantics of the newly-introduced ::draw signal are the same as the
one used by GTK+:

  - the signal is emitted on invalidation;
  - the cairo_t* context is owned by the actor;
  - it is safe to have multiple callbacks attached to the same
    signal, to allow composition;
  - the cairo_t* is already clipped to the invalidated area, so
    that Cairo can discard geometry immediately before we upload
    the texture data.

There are possible future improvements, like coalescing multiple
invalidations inside regions, and performing clipped draws during
the paint cycle; we could even perform clipped redraws if we know the
extent of the invalidated area.

cbe1e8321b tests: Dynamically resolve GL symbols
Some of the tests are making direct GL calls. Eventually we want
Clutter not to link directly against any GL library so that it can
leave Cogl to load it dynamically. As a step towards getting this to
work this patch changes the tests to resolve the symbols using
cogl_get_proc_address instead of linking directly.

123bd41e6c texture: Clean up error reporting
ClutterTexture relies too much on GError, even for things that are
clearly programmer errors. Also, no error message passed to GError
is marked for translation as it should.

We should move the programmer errors, like passing the wrong bpp
value with regards to the presence of the alpha channel, to real
warnings; we should also try and harmonize all the error messages,
and not mention Cogl — especially in the ones marked for translation.

672bc337ba build: don't explicitly include and egl or gl headers
This avoids explicitly including gl or egl headers in
clutter-egl-headers.h. We were getting build failures when building
clutter against a libcogl that has runtime support for GL and GLES
because cogl-defines.h was including gl.h and then clutter-egl-headers.h
was later including GLES2/gl.h with typedef conflicts. Clutter relies on
Cogl to abstract GL and GLES and the winsys APIs like EGL and GLX so
Clutter should just rely on cogl.h to include the appropriate egl.h in
clutter-egl-headers.h.

a4b9eaf3ec alpha: Don't use the GClosure to compute the alpha when possible
Setting up the call and calling the GClosure was showing up in profiles
and seemed an easy one to remove.

Instead of calling the closure, let's remember the alpha func and the
user_data when possible (ie set_mode() and set_func()) and use it in
get_alpha().

1402c05112 timeline: Cast elapsed time before emitting ::new-frame
When emitting a new-frame signal, priv->elapsed_time is passed as a
parameter. This is a gint64. The closure marshal uses an INT. On some
platforms, this is not received correctly by signal handlers (they
receive 0). One solution is to cast priv->elapsed_time to a gint when
emitting the signal.

We cannot change the signature of the signal without breaking ABI.

075a4ed86c x11: Improve XGenericEventCookie data allocation
https://bugzilla.gnome.org/show_bug.cgi?id=654656

Clutter may be used together with GTK+, which indirectly may use
XInput2 too, so the cookie data must persist when both are handling
events.

What happens now in a nutshell is, Clutter is only guaranteed to allocate
the cookie itself after XNextEvent(), and only frees the cookie if its
XGetEventData() call allocated the cookie data.

The X[Get|Free]EventData() calls happen now in clutter-event-x11.c as
hypothetically different event translators could also handle other set
of X Generic Events, or other libraries handling events for that matter.

c6a0427c69 pick: Use Cogl API not GL API to disable dithering
When picking we need to disable dithering to be sure that the hardware
will not modify the colors we use as actor identifiers. Clutter was
manually calling glEnable/Disable GL_DITHER to handle this, but that was
a layering violation since Cogl is intended to handle all interactions
with OpenGL. Since we are now striving for GL vs GLES to be a runtime
choice we need to remove this last direct usage of GL from Clutter so it
doesn't have to be linked with GL at build time.

3183240fef Provide stable paint-boxes for fixed sized actors
This updates _clutter_paint_volume_get_stage_paint_box to try and
calculate more stable paint-box sizes for fixed sized paint-volumes by
not basing the size on the volume's sub-pixel position.

So the aim is that for a given rectangle defined with floating point
coordinates we want to determine a stable quantized size in pixels that
doesn't vary due to the original box's sub-pixel position.

The reason this is important is because effects will use this API to
determine the size of offscreen framebuffers and so for a fixed-size
object that may be animated across the screen we want to make sure that
the stage paint-box has an equally stable size so that effects aren't
made to continuously re-allocate a corresponding fbo.

The other thing we consider is that the calculation of this box is
subject to floating point precision issues that might be slightly
different to the precision issues involved with actually painting the
actor, which might result in painting slightly leaking outside the
user's calculated paint-volume. This patch now adds padding to consider
this too.

df751a8a25 actor: improve rounding in get_allocation_geometry
Instead of relying on C to round the floating point allocation to
integers by flooring the values we now use CLUTTER_NEARBYINT to round
the allocation's position and size to the nearest integers instead. Using
floor leads to rather unstable rounding for the width and height when
there may be tiny fluctuations in the floating point width/height.

32487af55b Adds a CLUTTER_NEARBYINT macro for float rounding
This is a replacement for the nearbyint function which always rounds to
the nearest integer. nearbyint is a C99 function so it might not always
be available but also it seems in glibc it is defined as a function call
so this macro could end up faster anyway. We can't just add 0.5 because
it will break for negative numbers.

ad234b303c paint-volume: don't round paint-volume from allocation
The implementation of _clutter_actor_set_default_paint_volume which
simply uses the actor's allocation to determine a paint-volume was
needlessly using the allocation rounded to integers by internally using
clutter_actor_get_allocation_geometry instead of
clutter_actor_get_allocation_box. This was introducing a lot of
instability into the paint-volume due to the way rounding was done.

The code has now been updated to use clutter_actor_get_allocation_box
so we are dealing with the floating point allocation instead.

This adds a public function to get the bounds of the current clipped

ClutterStageWindow implementation. If the function isn't implemented
or it returns FALSE then the entire stage is reported. The clip bounds
are in integer pixel coordinates in the stage's coordinate space.
