86e4e89bf1 Rename ActorClone to Clone/2
Step two: rename the object and its methods.

While we're at it, adhere more strictly to the coding style
practises; rename :clone-source to :source; add a setter method
for the :source property; take a reference on the source actor
to avoid it disappearing while we're still accessing it.

8b39bfec7f Improves the unit test to verify more awkward scaling and some corresponding fixes
This simplifies the mucking about with the model-view matrix that was previously
done which improves its efficiency when scaling is necessary.

Notably: There should now be no performance advantage to using
ClutterCloneTexture as a special case clone actor since this method is just as
efficient.

The unit test was renamed to test-actor-clone.

df7480090d Implements a generic ClutterActorClone that doesn't need fbos.
Many use cases for clonning an actor don't require running a shader on the
resulting clone image and so requiring FBOs in these cases is overkill and
in-efficient as it requires kicking and synchronizing a render for each clone.

This approach basically just uses the paint function of another actor to
implement the painting for the clone actor with some fiddling of the model-
view matrix to scale according to the different allocation box sizes of
each of the actors.

A simple unit test called test-actors2 was added for testing.

6d4cd416ec Change default tile-waste from 64 to 63
It's more sensible to use 2^n-1 for a max tile-waste value rather
than 2^n, so change the value default from 64 to 63. Example:
191 and 192 will both be sliced to 128+64 rather than having
191=>128+64, 192=>256.

b716d32000 Fix properties that have X11 types to be 'long'
While X11 Pixmap and Window types only have 32-bits of data, they
are actually 'unsigned long'. Change the "window" and "pixmap"
property of ClutterX11TexturePixmaps to be ulong.

This fixes 64-bit bugs where ClutterGLXTexturePixmap passed a
reference to Pixmap to g_object_get("pixmap", &pixmap, ...);

10f1f6587e [eglnative] Set the SYNC_MATRICES on stage realization
Since the stage in the EGL native backend only has one size, and it
is determined at realization, we can simply set the SYNC_MATRICES
private flag and let _clutter_stage_maybe_setup_viewport() set up
the GL viewport at the first redraw.

c096f41e70 [doc] Clarify the animation mode meaning

d02819949d Remove AnimationMode from the Animation API
The animation mode symbolic id might come from the AnimationMode
enumeration or from the clutter_alpha_register_*() family of
functions. For this reason, we should use a gulong instead of
ClutterAnimationMode whenever we have an "animation mode" parameter
or property.

74213e0ee3 [alpha] Allow registering alpha functions
In order to unify alpha functions and animation modes in ClutterAlpha
we should be able to register alpha functions and get a logical id
for them; the logical id will then be available to be used by
clutter_alpha_set_mode().

The registration requires API changes in ClutterAlpha constructors
and methods. It also provides the chance to shift ClutterAlpha
towards the use of animations modes only, and to alpha functions
as a convenience API for language bindings alone.

642617b7a0 [test-text] queue redraws instead of calling clutter_actor_paint directly
Directly calling clutter_actor_paint skips out quite a bit code such as the
backend swap buffer call.

Since we are interested in the highest fps possible, and it now goes through
to the backend swap buffer call we now do a setenv (CLUTTER_VBLANK, none, 0)
before calling clutter_init.

22183c7a8f Bug 1380 - Return booleans from CLUTTER_ACTOR_IS_* macros
If you try to use the CLUTTER_ACTOR_IS_* macros defined in ClutterActor
like this:

  typedef struct { unsigned int reactive : 1; } foo_t;

  foo_t f; f.reactive = CLUTTER_ACTOR_IS_REACTIVE (actor);

It will blow up because while the macros evaluate to 0 they can also
evaluate to non-zero values. Since most of the boolean flags in
Clutter and Clutter-based code are going to be stored like in the
example above, we should change the macros and let them evaluate
stricly either to 0 or to 1.

d454bfcc87 [ClutterStageX11] Remove the handling_configure flag
Since Clutter changed to using a layout scheme the handling_configure
flag no longer works because the allocate method is not invoked
immediately during the call to set_size from the ConfigureNotify
handler. However it is also no longer neccessary because the resizes
are effectively batched up until a relayout is run so it won't cause
an infinite loop of resize and notify events anyway.

ffc15e0962 [clutter-text] Fix x-position of cursor when moving up or down
ClutterText already has code to try to preserve the x position when
moving up or down. A target x-position is stored and the cursor is
positioned at the nearest point to that in the appropriate line when
up or down is pressed. However the target position was never cleared
so it would always target the x-position of the cursor from the first
time you pressed up or down.

To fix this the patch clears the target position in set_position and
then sets it after the call in real_move_up/down. That way pressing
up or down sets the target position and any other movement will clear
it.

To get an index for the pixel position in the line
pango_layout_line_x_to_index is used. However when x is greater than
the length of the line then the index before the last grapheme is
returned which was causing it to jump to the penultimate
character. The patch makes it add on the trailing value so that it
will jump to the last character.

e93c266647 [clutter-text] Don't allow control characters to be inserted
If an unbound control key is pressed (such as Ctrl+R) it would insert
a rectangle into the text.

Also zero is considered a valid unicode character by
g_unichar_validate so pressing a key such as shift would cause the
current selection to be deleted. The character isn't actually inserted
because insert_unichar disallows zeroes.

de114dead7 Fix GLES 2 after the multiple-texture-rectangle branch merge
The GLES 2 wrapper needs to set up some state before each
draw. Previously this was acheived by wrapping glDrawArrays. Since the
multiple-texture-rectangle branch merge, glDrawElements is used
instead so we also need a wrapper for that.

It was also directly calling glBindTexture. GLES 2 uses a wrapper for
this function so that it can cope with GL_ALPHA format textures. The
format of the current texture needs to be stored as well as the target
and object number for this to work.

a9ae1c65c3 Add ClutterBindingPool:name
The BindingPool constructor should only check for duplicate pools
and then set the :name constructor-only property. If a BindingPool
is created without a name we also make a fuss about it.

It is also possible to simply dispose of a binding pool using
g_object_unref(), as long as it has been created by using
clutter_binding_pool_new() or directly with g_object_new(). Only
BindingPools attached to a class are not owned by the user.

a4c8a70c83 Turn ClutterBindingPool a GObject
ClutterBindingPool is already "problematic" in terms of memory
management for language bindings and gobject-introspection. It
also lacks a GType.

Turning ClutterBindingPool into a GBoxed would not make much
sense, since it does not adhere to the copy/free semantics. It
could be referenced/unreferenced, but in that case we can just
as well use GObject as a base class instead of reimplemeting
a ref-counted object and then boxing it.

ClutterBindingPool is obviously a terminal class, so we just
hide the instance and class structures.

5ed62aaf76 [async-loading] Do not force the texture size on async load

168d558bcf [async-loading] Update asynchronous image loading
Provide a main loop-based fallback to the asynchronous loading in
case the GLib threading support hasn't been enabled. This also
allows us to clean up the asynchronous loading machinery and have
it behave consistently across different scenarios.

Emit the ::load-finished even if the asynchronous loading from
disk was not enabled.

Finally, block clutter_texture_set_from_file() until we have an
image width and height, so that querying the texture actor size
after set_from_file() will still yield the correct result even
when asynchronous loading is set.

be462b2ea8 Bug 1087 - virtualize stage_queue_redraw
Add a ClutterStage::queue-redraw signal.

The purpose of this signal is to allow combining the Clutter redraw
idle with another redraw idle such as gtk's (or any other one really;
this is desirable anytime Clutter is not the only thing drawing to
a toplevel window).

To override the default, you would connect to ::queue-redraw and then
stop the signal emission.

f911a3a7a1 Allow ensuring that a stage viewport is updated
Since we only update the GL viewport when we receive a ConfigureNotify
event on X11, we also need a function to allow other toolkits to tell
a stage that the viewport should be updated.

This commit adds clutter_stage_ensure_viewport(), a function that simply
sets the private SYNC_MATRICES flag on the stage and then queues a
redraw.

This function should be called by libraries integrating Clutter with
other toolkits, like clutter-gtk or clutter-qt.

00a3c69868 [x11] Fix a race condition when resizing a stage
There is a race condition when we resize a stage before showing
it on X11.

The race goes like this:

  - clutter_init() creates the default stage and realize it, which
    will cause a 640x480 Window to be created
  - call set_size(800, 600) on the stage will cause the Window to be
    resized to 800x600
  - call show() on the stage for the first time will cause COGL
    to set up an 800 by 600 GL viewport
  - the Window will be mapped, which will cause X to notify the
    window manager that the Window should be resized to 800x600
  - the window manager will approve the resize
  - X resizes the drawable to 800x600

To fix the race, we need to defer COGL from setting up the viewport
until we receive a ConfigureNotify event and the X server has resized
the Drawable.

In order to defer the call to cogl_setup_viewport() we add a new
private flag, CLUTTER_STAGE_IN_RESIZE; the flag is checked whenever
we need to change the viewport size along with the SYNC_MATRICES
private flag. Thus, cogl_setup_viewport() will be called only if
SYNC_MATRICES is set and IN_RESIZE is not set.
