Projection lights

[Aloys]

Projection lights (lights that 'project' a texture like the folliage shadow on the outside of the well Garisson building) have been added in PyPRP recently, and Nadnerb just did a tutorial for using those here.
Those should be really usefull for dealing with complex shadows/lighting like tree shadows, or more sci-fi looking lights (like the GZ light beam)..
However I can't get spotlights to work.. I'm not sure what I'm doing wrong, because it work perfectly fine with area lights.
