529e48fbbe Remove duplicate cogl-internal.h header
The cogl-internal.h header has been moved inside cogl/common in
commit 8a1b4f8326 but has been left behind inside cogl/gl and
cogl/gles.

407ac5075f [texture] Add missing accessors
ClutterTexture has many properties that can only be accessed using
the GObject API. This is fairly inefficient and makes binding the
class overly complicated.

The Texture class should have accessor methods for all its properties,
properly documented.

3115a61688 [cogl] Rework the GL-error-to-string conversion
The code for the conversion of the GL error enumeration code
into a string is not following the code style and conventions
we follow in Clutter and COGL.

The GE() macro is also using fprintf(stderr) directly instead
of using g_warning() -- which is redirectable to an alternative
logging system using the g_log* API.

cd3acca2b7 [build] Link Cogl against -lm
We use math routines inside Cogl, so it's correct to have it in
the LIBADD line. In normal usage something else was pulling in
-lm, but the introspection is relying on linking against the
convenience library.

2f5012e38c [animation] Do not leak timelines
The timeline created when calling set_timeline(NULL) is referenced
even though we implicitly own it. When the Animation is destroyed,
the timeline is then leaked.

79cb0a3515 [animation] Remove InitiallyUnowned from Animation
ClutterAnimation currently inherits the initial floating reference
semantics from GInitiallyUnowned. An Animation is, though, meant to
be used as a top-level object, like a Timeline or a Behaviour, and
not "owned" by another object. For this reason, the initial floating
reference does not make any sense.

d8aa6827ee Don't build Cogl.gir against installed Clutter library
Passing:

 --library=clutter-@CLUTTER_FLAVOUR@-@CLUTTER_API_VERSION@

to g-ir-scanner, when building Cogl was causing g-ir-scanner to
link the introspection program against the installed clutter library,
if it existed or fail otherwise. Instead copy the handling from
the json/ directory where we link against the convenience library
to scan, and do the generation of the typelib later in the
main clutter/directory.

If text is set, ClutterText should never return less than the layout

This holds unless ellipsize and wrap are enabled, in which case the

the height needed to at the very least show the ellipsization.

2b1759385e [text] Ensure clutter_text_get_selection copes with start/end positions of -1
I was seeing clutter_text_get_selection trying to malloc up to 4Gb due to
unexpected negative arithmetic for the start/end offsets which resulted
in a crash.

This just tests for positions of -1 before deciding if the start/end

already works with -1.

d1fa83039d [picking] Use cogl_clip_push_window_rect to greatly reduce the cost of picking.
cogl_clip_push_window_rect is implemented using GPU scissoring which allows
the GPU to cull anything that falls outside a given rectangle.  Since in the
case of picking we only ever care about a single pixel we can get the GPU to
ignore all geometry that doesn't intersect that pixel and only rasterize for
one pixel.

e80fcbc298 [cogl-clip-stack] Support pushing rectangles onto the stack using window coords
Previously clipping could only be specified in object coordinates, now
rectangles can also be pushed in window coordinates.

Internally rectangles pushed this way are intersected and then clipped using
scissoring.  We also transparently try to convert rectangles pushed in
object coordinates into window coordinates as we anticipate the scissoring
path will be faster then the clip planes and undoubtably it will be faster
than using the stencil buffer.

36cfb60307 [cogl] Remove the COGL{enum,int,uint} typedefs
COGLenum, COGLint and COGLuint which were simply typedefs for GL{enum,int,uint}
have been removed from the API and replaced with specialised enum typedefs, int
and unsigned int. These were causing problems for generating bindings and also
considered poor style.

The cogl texture filter defines CGL_NEAREST and CGL_LINEAR etc are now replaced
by a namespaced typedef 'CoglTextureFilter' so they should be replaced with
COGL_TEXTURE_FILTER_NEAREST and COGL_TEXTURE_FILTER_LINEAR etc.

The shader type defines CGL_VERTEX_SHADER and CGL_FRAGMENT_SHADER are handled by
a CoglShaderType typedef and should be replaced with COGL_SHADER_TYPE_VERTEX and
COGL_SHADER_TYPE_FRAGMENT.

cogl_shader_get_parameteriv has been replaced by cogl_shader_get_type and
cogl_shader_is_compiled. More getters can be added later if desired.

8ca46d728d [build] Build Cogl introspection data
Currently, the introspection data for Cogl is built right into
Clutter's own typelib. This makes functions like:

  cogl_path_round_rectangle()

Appear as:

  Clutter.cogl_path_round_rectangle()

It should be possible, instead, to have a Cogl namespace and:

  Cogl.path_round_rectangle()

This means building introspection data for Cogl alone. Unfortunately,
there are three types defined in Cogl that confuse the introspection
scanner, and make it impossible to build a typelib:

  COGLint
  COGLuint
  COGLenum

These three types should go away before 1.0, substituted by int,
unsigned int and proper enumeration types. For this reason, we can
just set up the GIR build and wait until the last moment to create
the typelib. Once that has been done, we will be able to safely
remove the Cogl API from the Clutter GIR and typelib and let
people import Cogl if they want to use the Cogl API via introspection.

a5cdfdfd87 [cogl-offscreen] Cleans up the cogl offscreen API and adds documentation
There were several functions I believe no one is currently using that were
only implemented in the GL backend (cogl_offscreen_blit_region and
cogl_offscreen_blit) that have simply been removed so we have a chance to
think about design later with a real use case.

There was one nonsense function (cogl_offscreen_new_multisample) that
sounded exciting but in all cases it just returned COGL_INVALID_HANDLE
(though at least for GL it checked for multisampling support first!?)
it has also been removed.

The MASK draw buffer type has been removed. If we want to expose color
masking later then I think it at least would be nicer to have the mask be a
property that can be set on any draw buffer.

The cogl_draw_buffer and cogl_{push,pop}_draw_buffer function prototypes
have been moved up into cogl.h since they are for managing global Cogl state
and not for modifying or creating the actual offscreen buffers.

This also documents the API so for example desiphering the semantics of
cogl_offscreen_new_to_texture() should be a bit easier now.

e47b198225 add cogl_push_draw_buffer() and cogl_pop_draw_buffer()
These are necessary if nesting redirections to an fbo,
otherwise there's no way to know how to restore
previous state.

glPushAttrib(GL_COLOR_BUFFER_BIT) would save draw buffer
state, but also saves a lot of other stuff, and
cogl_draw_buffer() relies on knowing about all draw
buffer state changes. So we have to implement a
draw buffer stack ourselves.
