Clutter units are, at the moment, implemented as a value in fixed point
notation using the same format as CoglFixed. This is, though, an
implementation detail. For this reason, units should not be treated as
CoglFixed values and should be converted to and from fixed point using
the provided macros.
This commit updates the usage of units and fixed point values in
ClutterActor and rationalises some of the transformation code that
heavily relied on the equivalency between them.
Currently, the conformance test suite creates symbolic links pointing
to a wrapper script that just parses the name used to invoke it and
calls the gtester with the correct path.
Unfortunately, this presents two issues:
- it does not really work on file systems that do not
support symbolic links
- it leaves behind the symbolic links, which cannot
be automatically cleaning by 'make clean'
Both can be solved by creating a small script that invokes the wrapper
one with the test unit path.
The Makefile will use test-conform to extract the unit test paths
and generate a list that will be iterated over to create the
executable name (using the "test-name" convention also used by the
interactive tests, instead of "test_name"); the executable is then
just a simple shell script that invokes the wrapper script passing
the unit test path on the command line. The wrapper script will
use the first argument to work correctly, so it could be simply
executed like:
./test-wrapper.sh /path/to/unit_test
Which is another improvement over the current implementation, where
the wrapper script does not work when invoked directly.
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.
Since commit c7c5cf9b ClutterCloneTexture causes an extra paint of the
source actor during the paint run of the cloned texture if the source
is not yet visible. When the stage is first shown it is redrawn
immediatly before it is mapped which means get_paint_visibility will
fail on the source actor so the inner paint will be run. The paint
guards were a global variable so they didn't cope with a second actor
being painted.
The breakage didn't occur until commit d510a4b0 because
get_paint_visibility was also broken.
The ClutterParamSpecFixed constructor is declared in the header
as taking ClutterFixed values, but the implementation takes
ClutterUnit values instead. This obviously works because fixed
and units are exactly the same type.
This commit fixes the wrong parameters.
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.

* clutter/cogl/common/cogl-mesh.c: Rename the glBufferDataSub
function to glBufferSubData. When calling glXGetProcAddress with
the former Mesa returns a stub dispatch function which will
segfault if you try to use it. With NVIDIA it returns NULL so
_cogl_features_init decides the card doesn't have VBO support.

Don't set the depth if there is no x or y tilt. That way it can

key bindings for actors and then execute closures inside the
key-press-event signal handlers, removing the need for big
switch() or if() blocks for each key.

cogl_path_move_to. Previously this always started a new path but
now it instead starts a new disjoint sub path. The path isn't
cleared until you call either cogl_path_stroke, cogl_path_fill or
cogl_path_new. There are also cogl_path_stroke_preserve and

* clutter/cogl/common/cogl-clip-stack.c:
* clutter/cogl/common/cogl-clip-stack.h: Simplified the clip
stack code quite a bit to make it more maintainable. Previously
whenever you added a new clip it would go through a separate route
to immediately intersect with the current clip and when you
removed it again it would immediately rebuild the entire clip. Now
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
buttons add clips in different shapes. This makes it easier to
test multiple levels of clipping.
* tests/interactive/test-cogl-primitives.c: Use
cogl_path_stroke_preserve when using the same path again.

* clutter/cogl/gl/cogl-texture.c: Set the wrap mode of a texture
on demand
Instead of setting the wrap mode once per texture at creation, it
is now changed whenever the texture is drawn. The previous value
is cached so that it isn't changed if the value is the same.
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
rendered off-pixel.

that texture coordinates are in increasing order but this is not
the case since bug 1057 was fixed. The texture coordinates are now
sorted later. It also allowed negative coordinates which doesn't
make sense if the texture has waste.

* clutter/clutter-score.c (traverse_children): Don't destroy the
entry in the handler for REMOVE_BY_ID. It will be removed again
anyway in the call to g_node_traverse. This was causing a

detected in the configure script. A helper script is also
generated to setup the LD_PRELOAD.

test-report and full-report rules. test-report-normal is the same

disable-npots wrapper script. The full-report rule runs both of
them and displays two separate HTML files. The test-report rule
just runs the normal version as before.

Adds a wrap_mode member like GL has.
* clutter/cogl/gl/cogl-texture.c
* clutter/cogl/gles/cogl-texture.c:
Improves the comparability of the files, such that the remaining
differences, better reflect the fundamental differences needed
between GL and GLES. Notably GL no longer uses glBegin/glEnd for
submitting vertices, it uses vertex arrays like GLES and this gives
a small but measurable fps improvement for test-text.
* clutter/cogl/cogl-shader.h: Add a function for setting an
integer uniform, similar to cogl_program_uniform_1f().
* clutter/cogl/gl/cogl-program.c: Implement the GL version
