The TransitionGroup class is a logical container for running multiple
transitions.
TransitionGroup is not a Score: it is a Transition that advances each
Transition it contains using the delta between frames, and ensures that
all transitions are in a consistent state; these transitions are not
advanced by the master clock.
The get_distance() API uses machine integers to compute the distance;
this means that on 32bit we can overflow the integer size. This gets
hidden by the fact that get_distance() returns an unsigned integer as
well.
In reality, ClutterPath is an unmitigated mess, and the only way to
actually fix it is to break API.

Some of the Clutter code was using GL types for the primitive types
such as GLint and GLubyte and then passing these to Cogl. This doesn't
make much sense because the Cogl functions directly take native C
types. This patch just replaces them with either a native C type or a
glib type.
Some of the cogl conformance tests are trying to directly call GL for
example to test creating a foreign texture. These tests have been
changed to manually define the GL enum values instead of relying on a
GL header to define them.
This is necessary because Cogl may soon stop including a GL header
from its public headers.

Yes, it's not really the proper GL name for a linear-on-every-axis of a
texture plus linear-between-mipmap-levels minification filter, but it
has three redeeming qualities as a name:
- LINEAR_MIPMAP_LINEAR sucks, as it introduces GL concepts like
mipmaps in the API naming, while we're trying to avoid that;
- people using GL already know what 'trilinear' means in this context
without going all Khronos on their asses;
- we're using 2D textures anyway, so 'linear on two axes and linear
between mipmap levels' can be effectively approximated to
'trilinear'.
I mean, if even the OpenGL official wiki says:
Unfortunately, what most people think of as "trilinear" is not linear
filtering of a 3D texture, but what in OpenGL terms is GL_LINEAR mag
filter and GL_LINEAR_MIPMAP_LINEAR in the min filter in a 2D texture.
That is, it is bilinear filtering of each appropriate mipmap level,
and doing a third linear filter between the adjacent mipmap levels.
Hence the term "trilinear".

then the horse has already been flogged to death, and I don't intend to
be accused of necrophilia and sadism by flogging it some more.
Prior art: every single GL tutorial in the history of ever;
CoreAnimation's scaling filter enumerations.
If people want to start using 1D or 3D textures they they are probably
going to be using Cogl API directly, and that has the GL naming scheme
for minification and magnification filters anyway.
It's a bit late in the game for changing the emission of the paint
signal with actors that use paint nodes - mostly because we have both
implicit paint nodes (background color, content) and explicit paint
nodes (the paint_node virtual).
When we branch for 1.12 we can revert this change.
ClutterContent is an interface for creating delegate objects that handle
what an actor is going to paint.
Since they are a newly added type, they only hook into the new PaintNode
based API.
The position and size of the content is controlled in part by the
content's own preferred size, and by the ClutterContentGravity
enumeration.
ClutterScript should be able to automatically call gettext() and friends
on strings loaded from a UI definition, prior to passing the string to
the object it is constructing.
The basic implementation is trivial:
- set a translation domain on the ClutterScript instance
- mark the translatable strings inside the JSON data, like:
"property" : {
"translatable" : true,
"string" : "a translatable string"
}
The hard part is now getting the tools we use to extract the
translatable strings to understand the JSON format we use inside
ClutterScript.
This has been converted to a Cogl-based test in the cogl source tree
so there is no need to maintain it here anymore.

In a separate branch, this test has become quite complicated and
involves multiple files and its own configure options. Instead of
cluttering up the clutter source tree it has now been moved to its own
repo at:

It's the conformance test suite: there's no need to namespace the files,
just like there's no need to namespace the units.
This commit does not change the Cogl tests: they will be moved to Cogl
over time, and it's easier to do if we leave them as they are.
