6a8e108757 clutter-actor: Rename y1 to y_1 to avoid a compiler warning
Somebody somewhere decided it would be ok to define 'y1' as a global
function in math.h thus condemning us to repeatedly making commits to
fix these obnoxious compiler warnings about aliasing.

5de85051c3 Make sure GLX_SGI_swap_control is set up correctly
glXSwapIntervalSGI only affects buffer swaps to the
current GLX drawable.

That means that calling it once in clutter_backend_glx_get_features
isn't sufficent, so set it up in clutter_backend_glx_ensure_context to
make sure it affects buffer swaps for the current drawable.

f935270aa0 script: Do not allocate memory when not needed
When printing out the property value during a ClutterScript debug run we
generate the value's content using g_strdup_value_contents() - though we
do it unconditionally. The contents might not be printed (they most
likely won't, actually) and will be freed afterwards. This is
unnecessary: we can allocate the contents string after checking if we're
going to print out the debug note, thus avoiding the whole
allocation/free cycle unless strictly needed.

913c187f4e Switch texture units before calling _cogl_texture_set_filters()
When setting up the state for a layer, we need to switch texture
units before we do anything that might bind the texture, or
we'll bind the wrong texture to the previous unit.

d21b7522f8 Fix errors in keeping track of the stage bounding rectangle
* Add new clutter_geometry_union(), because writing union intersection
  is harder than it looks. Fixes two problems with the inline code in
  clutter_stage_glx_add_redraw_clip().

  1) The ->x and ->y of were reassigned to before using them to
     compute the new width and height.
  2) since ClutterGeometry has unsigned width, x + width is unsigned,
     and comparison goes wrong if either rectangle has a negative
     x + width. (We fixed width for GdkRectangle to be signed for GTK+-2.0,
     this is a potent source of bugs.)

* Use in clutter_stage_glx_add_redraw_clip()

* Account for the case where the incoming rectangle is empty, and don't
  end up with the stage being entirely redrawn.

* Account for the case where the stage already has a degenerate
  width and don't end up with redrawing only the new rectangle and not
  the rest of the stage.

The better fix here for the second two problems is to stop using a 0
width to mean the entire stage, but this should work for now.

9e0385304f build: Mark --with-json=internal as experimental
The system JSON-GLib installation should be the preferred way of parsing
JSON in Clutter. The internal copy is limited by re-synchronization from
upstream, and by the fact that upstream contains a fork of GScanner that
allows parsing escaped UTF-8. We should warn users compiling Clutter
with the internal copy, just like we warn about the internal image
backend.

7e700be7b8 build: Require xcomposite
The X11TexturePixmap actor uses XComposite API directly, without guards.
It has been doing so for a while, against the fact that we do check for
the XComposite extension - but we don't depend on it. As soon as you try
building Clutter on X11 without the XComposite extension available all
hell breaks loose.

The obvious fix is to make Clutter depend on XComposite - basically
ratifying what's the current state of things.

d2bb57c3b2 Emit a critical warning if features are not initialized
If you forgot to call clutter_init() then you currently end up with a
warning saying that the stage cannot be initialized because the backend
does not support multiple stages. Clearly not useful.

We can catch some of the missing initialization in the features API,
since we will likely end up asking for a feature at some point.

bf7e6ae587 Add error reporting for create_context() failures
We kind of assume that stuff will break well before during the
ClutterBackend::create_context() implementation if we fail to create a
GL context. We do, however, have error reporting in place inside the
Backend API to catch those cases. Unfortunately, since we switched to
lazy initialization of the Stage, there can be a case of GL context
creation failure that still leads to a successful initialization - and a
segmentation fault later on. This is clearly Not Good™.

Let's try to catch a failure in all the places calling create_context()
and report back to the user the error in a meaningful way, before
crashing and burning.

d735ac4807 model: Let get_n_columns() return a sane value
If you call get_n_columns() during the instance initialization phase but
before set_name()/set_types() have been called, you'll get a (guint) -1.
This is less than ideal.

If columns haven't been initialized we should just return 0, which was
the intent of the API since the beginning.

0a6497a3b6 model: Add a comment on the n_columns field type
To avoid another bug report like:

with a patch that gets applied without a proper review, resulting in a
bug like:

  http://bugzilla.openedhand.com/show_bug.cgi?id=2032

I should probably add a comment on why on earth we're using an integer
as the n_columns member of the ClutterModelPrivate structure, and why it
is important that it is initialized as -1.

de4abfac95 Revert "model: Use guint for the n_columns field"
The int storage, and the initial value of -1, is used as a guard when
subclassing ClutterListModel to allow the sub-class to call
clutter_model_set_names() and clutter_model_set_types().

c2faaa4f39 cogl-texture-2d: Determine format before checking texture support
When entering cogl_texture_2d_new_from_bitmap the internal format can
be COGL_PIXEL_FORMAT_ANY. This was causing _cogl_texture_2d_can_create
to use an invalid GL format type. Mesa apparently ignores this but it
was causing errors when Cogl is compiled with debugging under NVidia.

a25885edf2 Fix checks for out-of-bounds coordinates and repeats
Add a return result from CoglTexture.transform_quad_coords_to_gl(),
so that we can properly determine the nature of repeats in
the face of GL_TEXTURE_RECTANGLE_ARB, where the returned
coordinates are not normalized.

The comment "We also work out whether any of the texture
coordinates are outside the range [0.0,1.0]. We need to do
this after calling transform_coords_to_gl in case the texture
backend is munging the coordinates (such as in the sub texture
backend)." is disregarded and removed, since it's actually
the virtual coordinates that determine whether we repeat,
not the GL coordinates.

Warnings about disregarded layers are used in all cases where
applicable, including for subtextures.

40b43fd64a eglnative: Don't create a context if there already is one
If the EGL context is already created then we shouldn't try to create
another one. This was causing problems where one context would be
created from calling _clutter_feature_init and the other was created
from _clutter_backend_get_features. Cogl would set up its state using
the first context and then assume the state was still valid when the
second context became used so blending was not working correctly.
