830f2402d4 Merge branch 'more-texture-backends'
This adds three new texture backends.

- CoglTexture2D: This is a trimmed down version of CoglTexture2DSliced
  which only supports a single texture and only works with the
  GL_TEXTURE_2D target. The code is a lot simpler so it has a less
  overheads than dealing with slices. Cogl will use this wherever
  possible.

- CoglSubTexture: This is used to get a CoglHandle to represent a
  subregion of another texture. The texture can be used as if it was a
  standalone texture but it does not need to copy the resources.

- CoglAtlasTexture: This collects RGB and RGBA textures into a single
  GL texture with the aim of reducing texture state changes and
  increasing batching. The backend will try to manage the atlas and
  may move the textures around to close gaps in the texture. By
  default all textures will be placed in the atlas.

6b1b27d4f8 cogl-bitmap: Update the format after (un)premultiplying
The pixel format of the bitmap needs to have its premult flag cleared
or set after the premult conversion otherwise it may get converted
again.

191d20eb56 cogl-atlas-texture: Fix a cut and paste error when getting the height
There was a typo in getting the height of the full texture to check
whether the sub region fits so that it was using the width
instead. This was causing crashes when debugging is enabled for some
apps.

0ea25d661b event: Do not generate click count for SCROLL events
The ClutterScrollEvent structure does not have a click count field,
so Clutter should not generate the click count for events of type
CLUTTER_SCROLL.

15c6fef7e3 tests: Add a Valgrind suppression file
When running tests under Valgrind it would be useful to pass a
suppression file for the known one-off allocations done by Clutter
and by its dependencies. This trims the output of Valgrind and
improves the ability to actually spot leaks.

466b00a806 glx: Clarify *why* we need the dummy window
The reason why we have a dummy, offscreen Window when we create the
GLX context is that GLX does not like it when you ask the context for
features if it's not made current to a Drawable. Maybe in the future
it will allow us to do so, but right now we have to make do with what
GLX offers us.

e6a3b6ebe7 cogl-texture: Avoid copying the bitmap when premultiplying from a file
In cogl_texture_new_from_file we create and own a temporary
bitmap. There's no need to copy this data if we need to do a premult
conversion so instead it just does conversion before passing it on to
cogl_texture_new_from_bitmap.

59198b8ab8 cogl-texture: Split out _cogl_texture_prepare_for_upload
The Cogl atlas code was using _cogl_texture_prepare_for_upload with a
NULL pointer for the dst_bmp to determine the internal format of the
texture without converting the bitmap. It needs to do this to decide
whether the texture will go in the atlas before wasting time on the
conversion. This use of the function is a little confusing so that
part of it has been split out into a new function called
_cogl_texture_determine_internal_format. The code to decide whether a
premult conversion is needed has also been split out.

d8d728a8d7 Remove the SDL backend
The SDL API is far too limited for the windowing system needs of
Clutter; the status of the SDL backend was always experimental, and
since the Windows platform is supported by a native backend there is
no point in having the SDL backend around any more.

ae188d203c win32: Use a dummy window to support delayed stage creation
The Win32 backend now implements the create_context method which
creates a context and binds it to a 1x1 invisible window. That way
there will always be a context bound and the features can be retrieved
without creating the default stage. This reflects the changes in
1c6ffc8..b245d55 to the GLX backend.

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.

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.
