763fcabd8b build: Warn with --disable-conformance and --enable-gcov
When building Clutter without conformance test suite we ought to warn
the user that the coverage report is not going to be accurate.

5f5f6d825f build: Allow disabling the conformance test suite
When building Clutter for packaging on headless boxes it's pointless to
allow building the conformance test to be built (and run on 'make
check').

2d5eeba5d8 docs: Fixes for TimeoutPool and Frame sources
The TimeoutPool is not used by ClutterTimeline any more, so we need to
remove a sentence from its description. We also need to fix the gtk-doc
syntax errors.

046a4b8047 cogl: Use the colours of COGL_DEBUG=rectangles to debug batching
Instead of assigning a new colour to each quad of a batch, the
rectangle debugging code now assigns a new colour to each batch so
that it can be used to visually see what is being batched. The colour
is stored in a global variable that is reset during cogl_clear. This
improves the chances that the same colour will be used for a batch in
the next frames to avoid flickering.

92a375ab47 cogl-vertex-buffer: Fix disabling the texture arrays from previous prim
When setting up the state for the vertex buffer,
enable_state_for_drawing_buffer tries to keep track of the highest
numbered texture unit in use. It then disables any texture arrays for
units that were previously enabled if they are greater than that
number. However if there is no texturing in the VBO then the max used
unit would be left at 0 which it would later think meant unit 0 is
still in use so it wouldn't disable it. To fix this it now initialises
the max used unit to -1 which it should interpret as ‘no units are in
use’ so it will later disable the arrays for all units.

Thanks to Jon Mayo for reporting the bug.

da392e24a5 docs: Fix some of the examples for the animation docs
In the example for clutter_actor_animate the "x" and "y" properties
are floats so they need to be passed float values in the var args
otherwise it will crash. There was also a missing comma.

There were some other minor problems with the behaviours example which
would cause it not to compile.

52cb54f5fa cogl: Fix checks of the number of available texture units
We were checking the number of texture units against the GL enum that is
used in glGetInteger() to query that number. Let's abstract this in a
little function.

Took the opportunity to dig a bit on the usage of GL limits for the
number of texture (image) units and document our use of them. We'll need
something finer grained if we want to fully exploit texture image units
with a programmable pipeline.

87d19b8d18 cogl: Fix gl equivalent of blend string
An example of what could be the equivalent of
    "RBG = REPLACE(TEXTURE)
     A   = MODULATE(PREVIOUS,TEXTURE)"
using the ARB_texture_env_combine extension was given, but it seems that
a few typo were left:
    * remove a spurius GL_COMBINE_ALPHA
    * use the _ALPHA variant of SRCN and OPERANDN when setting up the
      alpha combiner

functions for that, so make good use of them.

de31cbf4f7 test-cogl-multitexture: use several materials with texture matrices
A small doubt has risen about the use of CoglTextureUnit in materials:
will texture matrices still work if we have several materials, each of
them having at texture on the same texture unit? The answer is yes!

test-cogl-multitexture has been extended to use 2 materials with about
the same setup except a little difference: the texture matrices for the
lightmaps rotate in opposite directions.

While at it, changed the rotation behaviour by an implicit animation
with a small additional bonus bling.

06d8ebb0ba cogl: Create CoglTextureUnit with its associated unit number
The index field of CoglTextureUnit was never set, leading to the
creation of units with index set to 0. When trying to retrieve a texture
unit by its index (!= 0) with _cogl_get_texture_unit(), a new one was
created as it could not find it back in the list of textures units:
ctx->texture_units.

8fc07c51a9 actor: Use GParamSpecUint for :opacity
The :opacity property is defined using a GParamSpecUchar. This usually
leads to issues with language bindings that don't have an 'unsigned
char' type and that need to explicitly handle the conversion between
G_TYPE_UCHAR and G_TYPE_INT or G_TYPE_UINT.

The property definition already specifies an interval size of [0, 255]
on the values; more importantly, GObject already implicitly transforms
between G_TYPE_UCHAR and G_TYPE_UINT (the GValue transformation
functions are registered at type system initialization time) so
switching between a GParamSpecUchar and a GParamSpecUint should not be
an ABI break.

I have tested a simple program using the opacity property before and
after the change and I cannot see any run-time warnings related to this
issue.

7fa7c4a1b6 animation: Transform if necessary
The Animation code does transformation of values between type A and A'
after checking for compatibility using g_value_type_compatible(). This
is incorrect: compatibility means that the two types can be copied. The
correct conversion should follow:

        if (compatible (type (A), type (A')))
          copy (A, A');
        else
          if (transformable (type (A), type (A')))
            transform (A, A');
          else
            error("Unable to trasform type A in A'");

The transformation might still fail, so we need to check for errors
there as well as a fall-through case.

94249efff7 animation: Check for value transformability
We should not just check for compatibility, but also for the ability to
transform a GValue of type A into another of type A'.

Usually compatibility is enough, especially if types can be
introspected beforehand; some times, though, we also need to check for
transformability as a type can provide the transformation functions
necessary for the operation.

a545f66a5c master clock: Improve the timeline advancement protection
The commit 1c69c61745 which improved the
protection against timeline removals during the master clock advancement
was only doing half the job - and actually broke the chaining of
animations inside the ::completed signal.

We cannot simply take a reference on the timelines and still use the list
held by the master clock because the do_tick() might result in the
creation of a new timeline, which gets added at the end of the list with
no reference increase and thus gets disposed at the end of the iteration.

We also cannot steal the master clock timelines list because a timeline
might be removed as the direct result of do_tick() and remove_timeline()
would not find the timeline, failing and leaving a dangling pointer
behind.

For this reason we copy the list of timelines out of the one that the
Master Clock holds, take a reference on each timeline, advance them all,
release the reference and free the list.

8a4b647154 x11: Re-enable XI1 extension keyboards
The extension keyboard support in XInput 1.x is hopelessly broken.

Nevertheless, it's possible to use some bits of it, as we prefer the
core keyboard events to the XInput events, thus at least having proper
handling for X11 key events on the Stage window.

94f9f3bd93 x11: Always handle core device events before XI events
The XI 1.0 layer is complementary to the X11 core devices handling; this
means that core events will still be emitted for the core pointer and
keyboard devices, and that secondary (floating) devices should be
handled on top of that.

Thus, the XI event handling code should be executed (if explicitly
compiled in and enabled) if the core device events have not been parsed.

Note: this is going away with XI2, which completely replaces both core and
XI1 events.

74dbcede25 win32: Experimental implementation of device support
Mostly lifted from the core pointer and keyboard X11 backend support.

The win32 backend registers two devices (a core pointer and a core
keyboard) and assigns them to the event structure when doing the
translation from native events to Clutter events.

patch.

8a579838d5 device: Unset the cursor actor when leaving the stage
When an InputDevice leaves a stage we set the stage member of

machinery will then be able to emit the ENTER event on the Stage.

25c6ebbb2c x11: Discard the LeaveNotify for off-stage ButtonRelease
If the user presses a button on a pointer device and then moves out the
Stage X11 will emit the following events:

  LeaveNotify ➔ MotionNotify ... ➔ ButtonRelease ➔ LeaveNotify

The second LeaveNotify differs from the first by the state field.

Unfortunately, ClutterCrossingEvent doesn't have a modifier_state field
like other events, so we cannot provide a way for programmatically
distinguishing them from a Clutter perspective. This is also an X11-ism
we might not even want to replicate on every backend with sane
enter/leave semantics.

For this reason we should check inside the X11 event processing if the
pointer device has already left the Stage and ignore the second
LeaveNotify.
