Detailed Description

MatrixMapperClass. Does the chore of computing the u-v coorinates for a projected texture. Note that this VP must be "baby-sat" by something external to ensure that its ViewToTexture transform is up-to-date. I use it in the TexProjectClass to implement projected textures.

NOTE: for projected textures, the equation for computing a valid ViewToTexture transform is as follows (assuming my usual column vectors, etc): -1 ViewToTexture = Projection * Mwrld-shadow * Mwrld-camera
