b4f9c8204d [docs] Various gtk-doc updates for Cogl
This hides a number of internal structs and enums from the docs, and moves
some functions to more appropriate sections as well as misc description
updates (mostly for the vertex buffer api)

d01e3cd802 [cogl-vertex-buffer] Some fixes for texturing and color arrays
Fixes some blending issues when using color arrays since we were
conflicting with the cogl_enable state + fixes a texture layer
validation bug.

Adds a basic textured triangle to test-vertex-buffer-contiguous.

a2168686b9 [cogl-texture] Move the destruction of the material to _finalize
Otherwise if the dipose method is called twice the material will
already be destroyed when texture_free_gl_resources is called so it

05c7e5a97c [cogl-texture] Fix offset to next quad when flushing the log
When the quad log contains multiple textures (such as when a sliced
texture is drawn) it dispatches the log with multiple calls to
flush_quad_batch and walks a pointer along the list of vertices.
However this pointer was being incremented by only one vertex so the
next quad would be drawn with three of the vertices from the last
quad.

a4de12dbe8 [clutter-texture] Fix the no_slice property
The 'no_slice' property means the texture should never be sliced. We
want cogl to create a texture with any amount of waste so we pass
max_waste as -1. However this got broken in commit 168d55 so that the
meaning got negated (no_slice enabled slicing).

6bc7f4c723 [actor] Force a relayout on set_parent()
The current code that handles the invariant that the new parent
of an actor needing a layout should also be queued for relayout
is hitting the short-circuiting we do in the queue_relayout()
method.

In order to fix this we can forcibly set the actor to need a
width/height request and an allocation; then we queue a relayout
on the parent.

9cf02bfdb9 [text] Rename :alignment to :line-alignment
The :alignment property is prone to generate confusion: developers
will set it thinking that the contents of a ClutterText will
automagically align themselves.

Instead of using the generic term :alignment, and following the
GTK+ convention, we should use a more specific term, conveying the
actual effect of the property: alignment of the lines with respect
to each other, and not to the overall allocated area.

e349642937 [clutter-texture] Unref the Cogl material on dispose

ee0bf5e26d [clutter-texture] Release the temporary ref taken when setting a texture
When setting the cogl texture, the ClutterTexture takes a reference to
the Cogl handle but the material takes an additional reference when it
is set as the layer. Nothing was unrefing the temporary reference so
the textures were being leaked.

49359407b0 [cogl-texture] Fix the count for the number of enabled arrays
The quad drawing code keeps track of the number of texture units that
have the tex coord array enabled so that in the next call it can
disabled any that are no longer enabled. However it was using 'i+1' as
the count but 'i' is already set to 'n_layers' from the previous for
loop.

Therefore it was disabling an extra texture unit. This doesn't
normally matter but it was causing GLES 2 to pointlessly realize an
extra unit.

e88de5f5fd Fix building GLES 2 after the material branch merge
- In cogl-material.h it directly sets the values of the
  CoglMaterialLayerCombineFunc to some GL_* constants. However these
  aren't defined in GLES 2 beacuse it has no fixed function texture
  combining. Instead the CGL_* versions are now used. cogl-defines.h
  now sets these to either the GL_* version if it is available,
  otherwise it directly uses the number.

- Under GLES 2 cogl-material.c needs to access the CoglTexture struct
  so it needs to include cogl-texture-private.h

- There are now #define's in cogl-gles2-wrapper.h to remap the GL
  function names to the wrapper names. These are disabled in
  cogl-gles2-wrapper.c by defining COGL_GLES2_WRAPPER_NO_REMAP.

- Added missing wrappers for glLoadMatrixf and glMaterialfv.

- Renamed the TexEnvf wrapper to TexEnvi because the latter is used
  instead from the material API.

edbe9a0377 [cogl-material] Always bind the new texture handle
Cogl previously tried to cache the currently bound texture when
drawing through the material API to avoid excessive GL calls. However,
a few other places in Cogl and Clutter rebind the texture as well so
this can cause problems.

This was causing shaped windows to fail in Mutter because
ClutterGLXTexturePixmap was binding a different texture to update it
while the second texture unit was still active which meant the mask
texture would not be selected when the shaped window was drawn
subsequent times.

Ideally we would fix this by providing a wrapper around glBindTexture
which would affect the cached value. The cache would also have to be
cleared if a selected texture was deleted.

6e12722a9b [clone] Allow cloning unparented actors
If the source of a ClutterClone does not have a parent actor the
clone will be unable to paint it because it's missing an allocation.

A simple way to fix it is to make the ClutterClone act like a
"foster parent": when it is allocated it will check if the source
actor has a parent and if not it will allocate the source with
its preferred size.

801e535e94 Add Actor::create_pango_layout()
Final bit of integration between ClutterActor and Pango: a simple
method for creating a PangoLayout, pre-filled with text and ready
to be rendered using cogl_pango_render_layout().

This should make writing new Actors rendering custom text in their
paint() implementation easy and reliable.

488de99fc6 [text] Merge the attributes with markup enabled
ClutterText should merge the PangoAttributes set by using
clutter_text_set_attributes() with the attributes generated by
parsing Pango markup.

For this to work we must parse the markup and merge the attributes
we get out of pango_parse_markup() with the attributes set by
the user.

Setting the markup or the attributes on an editable text should
not work for the time being.

set_from_4d because taking doubles implies higher precision. Currently
it doesn't have any advantage.

ef4052c18d Changes cogl_rectangle to take x1, y1, x2, y2 args not x1, y1, width, height
This makes it consistent with cogl_rectangle_with_{multi,}texture_coords.
Notably the reason cogl_rectangle_with_{multi,}texture_coords wasn't changed
instead is that the former approach lets you describe back facing rectangles.
(though technically you could pass negative width/height values to achieve
 this; it doesn't seem as neat.)

with debugging texture slicing issues or blending issues, plus it looks quite

3e68b23ea8 Merge branch 'scale-center'
Bug 1349 - Using the anchor point to set the scale center is messy

The branch adds an extra center point for scaling which can be used
for example to set a scale about the center without affecting the
position of the actor.

The scale center can be specified as a unit offset from the origin or
as a gravity. If specified as a gravity it will be stored as a
fraction of the actor's size so that the position will track when the
actor changes size.

The anchor point and rotation centers have been modified so they can
be set with a gravity in the same way. However, only the Z rotation
exposes a property to set using a gravity because the other two
require a Z coordinate which doesn't make sense to interpret as a
fraction of the actor's width or height.

d7c275f5e5 [cogl-texture] Fix order of tex coords when compensating for waste
When drawing a texture with waste in _cogl_multitexture_unsliced_quad
it scales the texture coordinates so that the waste is not
included. However the formula was the wrong way around so it was
calculating as if the texture coordinates are ordered x1,x2,y1,y2 but
it is actually x1,y1,x2,y2.

eda1d08f76 Fix rectangles_with_multitexture_coords for sliced without tex coords

6b9da72ab0 Directly set backend font options in clutter_set_font_flags
Instead of having a separate set of font options that override the
backend options when clutter_set_font_flags is called, it now just
directly sets the backend font options. So now the font flags are just
a convenience wrapper around the backend font options.

This also makes the ClutterText labels automatically update when the
font flags are changed because they will respond to the 'font-changed'
signal from the backend.

89b0b00dd1 Listen for the font-changed signal on the backend in ClutterText
Whenever a ClutterText is created it now connects to the font-changed
signal. When it is emitted the layout cache is dirtied and a relayout
is queued. That way changes to the font options or resolution will
cause an immediate update to the labels in the scene.
