Matrix Stack

Class and utility classes for matrix stacks.

A common task in OpenGL programs is to have a stack of transforms. This is useful for hierarchial rendering and for traversing a scene graph. Indeed, OpenGL before 3.1's removal of old features had matrix stacks built in.

Since it is a very useful feature, the GL Util library provides the MatrixStack class. It also provides the PushStack class for RAII-style pushing and poping operations.
