The file is terribly out of date, and needs modifications to work with the current pyglet (it was developed pre-alpha, before several API changes). The core idea in the collision function there is to use OpenGL query objects to determine a list of sprites that are drawn over a stenciled area (which can be any shape). It's a pretty strange way to do things, and (as suggested by its location) entirely experimental. >From memory it worked fine, but it requires OpenGL 1.5 or later (many older cards won't have this support). For mouse selection (testing an irregular area against a point or rectangular area), you're better off using GL selection buffers -- there are many code examples of this around; I'm sure someone on this list will have some handy.
