27 * Matrix/vertex/vector transformation stuff
31 * 1. 4x4 transformation matrices are stored in memory in column major order.
32 * 2. Points/vertices are to be thought of as column vectors.
33 * 3. Transformation of a point p by a matrix M is: p' = M * p

73 /* Raw data format used for:
74 * - Object-to-eye transform prior to culling, although this too
75 * could be culled under some circumstances.
76 * - Eye-to-clip transform (via the function above).
78 * - And everything else too, if culling happens to be disabled.
80 * GH: It's used for everything now, as clipping/culling is done
81 * elsewhere (most often by the driver itself).
