* 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.
