Sebastian Dröge e87fa73e60 compositor: Implement different operators via per-pad property ... This removes the crossfade-ratio property and replaces it with an operator property. Currently this implements the following operators: - SOURCE: Copy over the source and don't look at the destination - OVER: Default blending of the source over the destination - ADD: Like OVER but simply adding the alpha instead See the example for how to implement crossfading with this. https://bugzilla.gnome.org/show_bug.cgi?id=797169		2018-10-28 17:13:26 +00:00
