ac-vector

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.) Changes: * Fixed a stupid bug in @union@. Until now, the function could sometimes return gibberish answers. Hopefully this is now fixed.
