Jonas Ådahl 64c3b824fa tests/clutter: Use a dummy actor for some interactive tests
While completely untested, at least this makes it work "in theory"
again. Before it'd listen to signals on the stage, but have an incorrect
type signature to handle the test paint procedures, meaning it'd
probably crash or cause memory corruptions.

What was needed was a signal which in the callback the test could call
some cogl functions to paint on the framebuffer. While there is no such
signal on the stage, and the ClutterActor::paint signal (which they
probably used in the past) is long gone, lets add a "test actor" that is
just a wrapper that adds that paint signal with a paint context.

The tests that need it are changed to add this actor to the stage, and
to listen to the paint signal on the actor instead of incorrectly
listening on stage signals.

Outline of test categories:

The conform/ tests should be non-interactive unit-tests that verify a single
feature is behaving as documented. Use the GLib and Clutter test API and macros
to write the test units. The conformance test suites are meant to be used with
continuous integration builds.

The performance/ tests are performance tests, both focused tests testing single
metrics and larger tests. These tests are used to report one or more
performance markers for the build of Clutter. Each performance marker is picked
up from the standard output of running the tests from strings having the form
"\n@ marker-name: 42.23" where 'marker-name' and '42.23' are the key/value pairs
of a single metric. Each test can provide multiple key/value pairs. Note that
if framerate is the feedback metric the test should forcibly enable FPS
debugging itself. The file test-common.h contains utility function helping to
do fps reporting.

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 conform/ directory.

The accessibility/ tests are tests created to test the accessibility support of
clutter, testing some of the atk interfaces.

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. Tests for specific
bugs should reference the bug report URL or number.

• When running tests under Valgrind, you should follow the instructions
available here:

        https://wiki.gnome.org/Valgrind

and also use the suppression file available in the Git repository.
