Decided might be better to cover crossing and motion under
a broader "pointer motion" recipe, so renamed the example
(which only shows pointer crossing event handling).
It can be useful to be able to forcibly break the grab set up by the
ClickAction. The newly added release() method provides a mechanism to
release the grab and unset the :held state of the ClickAction.
This clarifies the documentation for clutter_actor_queue_redraw to
explain that custom actors should call this whenever some private state
changes that affects painting *or* picking.
The expectation is that actors should call clutter_actor_queue_redraw
when ever some private state changes that affects painting *or* picking.
ClutterTexture was not doing this for pick_with_alpha property changes.
The idea is that if we see multiple picks per frame then that implies
the visible scene has become static. In this case we can promote the
next pick render to be unclipped so we have valid pick values for the
entire stage. Now we can continue to read from this cached buffer until
the stage contents do visibly change.
Thanks to Luca Bruno on #clutter for this idea!
The tests/accessibility, tests/micro-bench and the examples directory
in the coobook create a lot of non-installed binaries. Since we know who
they are, and we ignore them, we can auto-generate the ignore files as
well.
The rest of Clutter is covered by the main ignore file.
Weak materials are ones that don't take a reference on their parent and
they are associated with a callback that notifies when the material is
destroyed, because its parent was freed or modified.

For now the concept is internal only but the plan is to make this public
at some point once we have tested the design internally.

This removes all references to SDL in the build instructions as the
backend is no longer available. The OpenGL version required is only
1.2 not 1.4. The Windows build instructions were out of date and have
been replaced with a link to the wiki instead.
Following the commits:
c03544da - clutter-shader: use cogl_program_set_uniform_xyz API
a26119b5 - tests: Remove use of cogl_program_use
Remove the users of cogl_program_uniform_* and cogl_program_use() in the
shader-based effects.
In the case where there is no error log for arbfp we were returning a
"" string literal. The other paths were using g_strdup to return a
string that could be freed with g_free. This makes the arbfp path return
g_strdup ("") instead.
There are quite a few if {} else {} blocks for dealing with arbfp else
glsl and the first block is guarded with #ifdef HAVE_COGL_GL. In this
case though the #endif was before the else so it wouldn't compile for
gles.
We need to include cogl-shader-private.h to have the
COGL_SHADER_TYPE_GLSL define. When building for opengl this wasn't
noticed probably because some other header indirectly includes this
file. It was a problem when building for gles2 though.
The removes the use of cogl_program_use which has been deprecated and
instead of using the cogl_program_uniform functions we now use the
cogl_program_set_uniform methods.
Instead of using the deprecated cogl_program_uniform_xyz functions we
now use the cogl_program_set_uniform methods. It looks like this should
also fix a problem with clutter-shader too in that previously we weren't
calling cogl_program_use before cogl_program_uniform_xyz so setting
uniforms would only work while the shader is enabled.
Instead of exposing an API that provides an OpenGL state machine style
where you first have to bind the program to the context using
cogl_program_use() followed by updating uniforms using
cogl_program_uniform_xyz we now have uniform setter methods that take an
explicit CoglHandle for the program.
This deprecates cogl_program_use and all the cogl_program_uniform
variants and provides the following replacements:
cogl_program_set_uniform_1i
cogl_program_set_uniform_1f
cogl_program_set_uniform_int
cogl_program_set_uniform_float
cogl_program_set_uniform_matrix
--quiet has been added to g-ir-scanner in the 0.9.1 cycle. We really
want to be able to compile clutter with 0.6.14 to be able to reuse
gir files that are distributed in current distributions.
Use the INTROSPECTION_SCANNER_ARGS (previously unused) variable to
convey --quiet when necessary.
