wipe transitions

Submitted by Jeff F.T. Assigned to Jeff F.T. @jeff
Description
Implement fancy heart/star/poney/whatever shaped transitions, maybe with the gstreamer "shapewipe" element (and/or opengl-powered transitions maybe).
This is more complex to implement than crossfades (which are done with videomixing so far) and less commonly required in prosumer/professional editing, thus lower priority. Anyone willing to tackle this task is more than welcome, however.
