4e493d1937 Avoid masking math.h exported variables
Our beloved math.h exports, from bits/mathcalls.h, a bare "y1" symbol.
Apparently, it's unthinkable for code including <math.h> to also declare
arguments or variable named "y0", "y1" and "yn".

Anyway, the quick fix already used elsewhere in Clutter's codebase is
to rename the colliding variables "y_0", "y_1" and "y_n" - and
obviously everything similar to them as well, using the same pattern.

81541e6940 [docs] Parameter naming fixes
The name of the parameter in the header and the one in the gtk-doc
annotation on top of a function must match.

Unfortunately, there is an index() function declared inside strings.h
which makes gcc complain for the "index" argument as soon as we
enable the extra compiler flags we use when distchecking.

Hence, we need to rename "index" to "index_" in the header and in
the source files.

64de0411ea [cairo-texture] Remove the construct only restriction on surface size
It is possible to change the surface size after construction with
clutter_cairo_texture_set_surface_size so it doesn't seem right to
restrict changing the properties.

clutter_cairo_texture_resize_surface_internal is called in a handler
for the notify signal. It is called there rather than directly in the
set_property handler so that changing both properties in a single
g_object_set will only cause one resize. The constructed override is
no longer needed.

resize_surface_internal will now bail out if the size of the surface
is already the right size.

5e0daa8ecd Improves tfp performance on Nvidia
Some drivers (e.g. Nvidia) get upset if you try to create multiple glx pixmaps
for the same server side pixmap object, even though you might have unique
client side names, we now avoid hitting this problem by destroying the current
glx pixmap early within clutter_glx_texture_pixmap_create_glx_pixmap.

4168ed09de Fix calculation in clutter_cubic_bezier
The calculation for cubic bezier curves had an extra multiplication by
3 which was causing the curve to go over 1.0 very quickly. This had
the affect of making test-animation appear to complete much before the
completed signal is emitted.

2bf815131a [clutter-interval] Fix calculation of interval for unsigned types
The patch makes it cast to double before subtracting the original
value from the target value. Otherwise if the target value is less
than the original value then the subtraction will overflow and the
factor will be multiplied by a very large number instead of the
desired interval.

The problem is demonstrable using the border-width property of
ClutterRectangle.

e130e0c9b3 [cairo-texture] Silently discard 0x0 surfaces
The current CairoTexture can be created with a surface size of 0
by 0 pixels, but a warning will be printed.

Worse, the surface can be resized to be 0 by 0 pixels without a
warning. The :surface-width and :surface-height properties accept
a minimum value of 0, and not check is performed on either the
constructor or set_surface_size() parameters to enforce the "greater
than zero" rule.

The correct and consistent behaviour is to allow a 0 by 0 pixels
surface size everywhere; inside surface_resize_internal(), the
current surface will be destroyed and if either :surface-width or
:surface-height are set to 0, the resizing terminates.

Attempting to create a Cairo context from a CairoTexture with
either :surface-width or :surface-height set to 0 will result in
a warning.

This allows:

  - creating a CairoTexture with :surface-width or :surface-height
    set to zero and delaying the surface resize at a later point;
  - resizing the surface to 0 by 0 pixels to destroy the image
    surface used internally;
  - increase the consistency in the usage of CairoTexture.

ff92cc9766 Convert clutter_path_get_position to take a gdouble instead of an alpha value
The gdouble value represents an interval along the path from 0.0 to
1.0. This makes more sense than using an alpha value because paths are
not directly related to ClutterAlphas and the rest of the Clutter API
tends to expose gdouble arguments.

f6feed4386 Fix a typo in the ClutterParamSpecFixed declaration
The ClutterParamSpecFixed constructor is declared in the header

ClutterUnit values instead. This obviously works because fixed

0e1a3c2124 Warn instead of returning in the IN_PAINT check
It's conceivable that a warning should be deemed enough, instead
of just returning a NULL cairo_t when creating a context for the

cf9dea7cf6 Print a warning when creating a cairo_t while painting
If you create a Cairo context in the middle of a paint run and then
you destroy it, the CairoTexture will have to upload the contents of
the image surface to the GL pipeline. This usually leads to slow
downs and general performance degradation.

ClutterCairoTexture will warn to the console if Clutter has been
compiled with the debug messages and if create() or create_region()
are called while an actor is in the middle of a paint.

1b88122873 Do not set the IN_PAINT flag inside the Stage paint
Since the CLUTTER_ACTOR_IN_PAINT private flag is set as part
of the paint process by clutter_actor_paint(), there is no
need to set it inside the ClutterStage paint function.

3f2c9fe6b3 Set the IN_PAINT private flag
When calling clutter_actor_paint() we should be setting the
CLUTTER_ACTOR_IN_PAINT private flag. This allows signalling
to each Actor subclass that we are effectively in the middle
of a paint sequence. Actor subclasses can check for this
private flag and act based on its presence - for instance to
avoid recursion, or to detect performance degradation cases.

e934ad03ca Add ClutterCairoTexture
Move the ClutterCairo actor from a separate library to an in-tree
actor.

ClutterCairoTexture is a simple texture subclass that allows you
to retrieve a Cairo context for a private image surface. When the
Cairo context is destroyed it will cause the image surface
contents to be uploaded to a GL texture.

The image surface used is not hardware accelerated.

bc6a107ff6 Do not modify parameters in place
When the apply_transform_to_point() and its relative variant
landed in Clutter 0.3, the initial approach was to modify the
passed vertex as an in-out parameter. This was later dropped
in favour of a more consistent out parameter.

Unfortunately, the implementation never changed: both methods
where modifying the passed vertex with the partial results of
the computations.

This commit copies the contents of the "point" ClutterVertex
argument inside a stack variable and, for good measure, constifies
the argument.

Thanks to Thomas Steinacher for catching this in Python.

	when you add or remove a clip it doesn't do anything immediately
	but just sets a dirty flag instead.

	* clutter/cogl/gl/cogl.c:
	* clutter/cogl/gles/cogl.c: Taken away the code to intersect
	stencil clips when there is exactly one stencil bit. It won't work
	with path clips and I don't know of any platform that doesn't have
	eight or zero stencil bits. It needs at least three bits to
	intersect a path with an existing clip. cogl_features_init now
	just decides you don't have a stencil buffer at all if you have
	less than three bits.

	* clutter/cogl/cogl.h.in: New functions and documentation.

	* tests/interactive/test-clip.c: Replaced with a different test
	that lets you add and remove clips. The three different mouse

55cec1f651 Bug 1305 - NPOT textures unaligned to a pixel sometimes have
border artifacts

	* clutter/cogl/gl/cogl-texture.c: Set the wrap mode of a texture

	Instead of setting the wrap mode once per texture at creation, it

	This is used in _cogl_texture_quad_hw to only enable GL_REPEAT
	mode when the coordinates are not in the range [0,1]. Otherwise it
	can pull in pixels from the other edge when the texture is
