Detailed Description

Manages global transform matrices and their combinations. Input transforms are the view transform (transforms from world to view space), the projection transform (describes the projection from view space into projection space (pre-div-z)) and the current model matrix (transforms from model to world space). From these input transforms, the TransformDevice computes all useful combinations and inverted versions.
