* clutter/x11/clutter-backend-x11.c: * clutter/clutter-event.h: * clutter/clutter-feature.h: * clutter/clutter-fixed.c: * clutter/clutter-model.h: Fix documentation. * clutter/eglnative/clutter-backend-egl.[ch]: * clutter/eglnative/clutter-event-egl.c: Add the same solution used for the SDL backend in order to get the time of an event. This should fix the motion event throttling and the click count on button press. * tests/test-pixmap.c (create_pixmap), (main): Fix preprocessor directives.
