d2c091e62d glx: Create the dummy Window with the GLX context
Since we must guarantee that Cogl has a GL context to query, it is too
late to use the "dummy Window" trick from within the get_features()
virtual function implementation.

Instead, we can create a dummy Window from create_context() itself and
leave it around - basically trading a default stage with a dummy X
window.

We need to have the dummy X window around all the time so that the
GLX context can be selected and made current.

cb52581a24 text: Add :font-description
High level toolkits might wish to construct a PangoFontDescription and
then set it directly on a ClutterText actor proxy or sub-class.
ClutterText should have a :font-description property to set (and get)
the PangoFontDescription.

74c0170ccc cogl-vertex-buffer: Refix disabling texture coord arrays
Commit 92a375ab4 changed the initial value of max_texcoord_attrib_unit
to -1 so that it could disable the texture coord array for the first
texture unit when there are no texture coords used in the vbo. However
max_texcoord_attrib_unit was an unsigned value so this actually became
G_MAXUINT. The disabling loop at the bottom still worked because
G_MAXUINT+1==0 but the check for whether any texture unit is greater
than max_texcoord_attrib_unit was failing so it would always end up
disabling all texture units. This is now fixed by changing
max_texcoord_attrib_unit to be signed.

301863d43b text: Fixes for selection bound
The commit ecbb7ce41a exposed some issues
when positioning the cursor with the mouse pointer: the selection is
not moved along with the cursor when inserting a single character or a
string.

Also, some freeze_notify() are called too early, leading to decoupling
from their respective thaw_notify().

c9a6e63fa4 docs: Clarify Group's sizing semantics
The documentation for ClutterGroup behaviour when setting an explicit
size is not accurate - or, actually, it was accurate by the time
ClutterGroup was first written but has been neglected in the following
release cycles.

To avoid confusion for new users of Clutter the documentation should be
slightly expanded, mentioning the exact semantics of ClutterGroup with
regards to: preferred size, explicitly set size and how to constrain the
visible area of a ClutterGroup to an explicitly set size.

12b004b0e7 tests: Add an initial Behaviour conformance suite
The coverage of the Behaviour sub-classes is currently abysmal. An
initial test suite for Behaviours should at least verify that the
accessors and the constructors are doing the right thing.

This initial test suite just verifies the BehaviourOpacity sub-class,
but it already bumps up the overall coverage by 2%.

521d71d4bc event: Unify the off-stage motion events delivery behaviour
When we disable the per-actor events delivery Clutter replicates the X11
implicit soft grab for motion events with off-stage. The implicit grab
is done whenever the pointer of a device leaves a window with a button
still pressed; with the implicit grab in place the window still receives
motion events even after the LeaveNotify - until the button is released.

The implicit grab is not honoured in the per-actor event deliver case,
though, so we have a mismatch between two in theory equivalent cases.

Luckily, the fix is pretty trivial: when we check for a motion event
with a stage set but without an actor set, and that has off-stage
coordinates, we arbitrarily set the source to be the stage of the event
and emit the pointer event.

abe91784c4 cogl: Let GL do the format conversion when uploading texture data
Cogl accepts a pixel format for both the data in memory and the
internal format to be used for the texture. If they do not match then
it would convert them using the CoglBitmap functions before uploading
the data. However, GL also lets you specify both formats so it makes
more sense to let GL do the conversion. The driver may need the
texture in a specific format so it may end up being converted anyway.

The cogl_texture_upload_data functions have been removed and replaced
with a single function to prepare the bitmap. This will only do the
premultiplication conversion because that is the only part that GL
can't do directly.

e83ffb1fa3 cogl: Do the premult conversion in-place rather than copying to a new buffer
The premult part of _cogl_convert_premult has now been split out as
_cogl_convert_premult_status. _cogl_convert_premult has been renamed
to _cogl_convert_format to make it less confusing. The premult
conversion is now done in-place instead of copying the
buffer. Previously it was copying the buffer once for the format
conversion and then copying it again for the premult conversion. The
premult conversion never changes the size of the buffer so it's quite
easy to do in place. We can also use the separated out function
independently.

72fba19eac cogl-atlas-texture: Use a single atlas for both RGB and RGBA textures
The internal format of the atlas texture is still set to the
appropriate format so Cogl will disable blending for textures that are
intended to be RGB. This should end up ignoring the alpha channel from
the texture in the atlas. This makes the code slightly easier to
maintain and should also improve the chances of batching.

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.

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

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

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.

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.

Usually compatibility is enough, especially if types can be

necessary for the operation.
