Video of the element:

The python script from the video:

This element needs the graphene library as a soft dependency:

The release plan for this is "around GUADEC" according to ebassi.
Graphene will be beneficial for all opengl plugins, or things which need linear
algebra.

Looking forward to comments and review.
