@hackage AC-Vector2.2.0

Efficient geometric vectors and transformations.

This Haskell library implements several small vectors types with Double fields, with seperate types for each size of vector, and a type class for handling vectors generally. (Note that although this package is listed in the "graphics" category, the package itself has no graphics facilities. It just contains data structures that are useful for graphics work.) Removed gather modules. Some name changes for bounding boxes.
