ClutterEffect is an abstract class that should be used to apply effects on generic actors. The ClutterEffect class just defines what an effect should implement; it could be defined as an interface, but we might want to add some default behavior dependent on the internal state at a later point. The effect API applies to any actor, so we need to provide a way to assign an effect to an actor, and let ClutterActor call the Effect methods during the paint sequence. Once an effect is attached to an actor we will perform the paint in this order: • Effect::pre_paint() • Actor::paint signal emission • Effect::post_paint() Since an effect might collide with the Shader class, we either allow a shader or an effect for the time being. |

Outline of test categories:
The conform/ tests should be non-interactive unit-tests that verify a single
feature is behaving as documented. See conform/ADDING_NEW_TESTS for more
details.
The micro-bench/ tests should be focused perfomance test, ideally testing a
single metric. Please never forget that these tests are synthetec and if you
are using them then you understand what metric is being tested. They probably
don't reflect any real world application loads and the intention is that you
use these tests once you have already determined the crux of your problem and
need focused feedback that your changes are indeed improving matters. There is
no exit status requirements for these tests, but they should give clear
feedback as to their performance. If the framerate is the feedback metric, then
the test should forcibly enable FPS debugging.
The interactive/ tests are any tests whose status can not be determined without
a user looking at some visual output, or providing some manual input etc. This
covers most of the original Clutter tests. Ideally some of these tests will be
migrated into the conformance/ directory so they can be used in automated
nightly tests.
The data/ directory contains optional data (like images and ClutterScript
definitions) that can be referenced by a test.
Other notes:
• All tests should ideally include a detailed description in the source
explaining exactly what the test is for, how the test was designed to work,
and possibly a rationale for the approach taken for testing.
• When running tests under Valgrind, you should follow the instructions
available here:
http://live.gnome.org/Valgrind
and also use the suppression file available inside the data/ directory.
