We should initialize and restore GIMP also in gimp_init_for_testing(),
not only in gimp_init_for_gui_testing(), because also non-UI tests
needs e.g. plug-ins to be available.
Introduce a few pixels of error margin in sessionrc, otherwise the
tests are too fragile, widgets have a tendency to change size a bit
and window managers have a tendency to move windows a bit.
Still needs more work, should probably do the same on book positions
too...
Instead of including dialogs/dialogs.h everywhere, introduce
gimp_dialog_factory_get_singleton(). The dialog factory singleton is
still initialized by dialogs.c though.
Right now the assumption is that we never will have another dialog
factory instance around. There were so many problems before when we
had four of them, so let's just keep one of them around.
Add gimp_test_run_temp_mainloop() which is a helper function for tests
that wants to run a main loop for a while. Useful when you want GIMP's
state to settle before doing tests.
In order to allow test cases to test GUI code, add
gimp_init_for_gui_testing() which is like gimp_init_for_testing() but
includes initializations of GUI parts.
* tests.[ch]: initialize base so we have a tile cache and add
parameter "gboolean use_cpu_accel" so we can test stuff both with
and without using CPU features.
* tests/test-layer-grouping.c: changed accordingly. Call g_thread_init()
so the tile cache works (and to be on the safe side in general).
Enable us to have regression testing by introducing a core testing
framework that uses the GLib JUnit-like test library.
Do this by adding a new subdir app/tests that will contain all our
tests (it contains one trivial test already). Also add app/tests.[ch]
with a new function gimp_init_for_testing() so that test cases can
easily setup the core object system.
