KINDS OF TRANSFORMS:

TransformXRotation1:
Single rotation/translation in the plane spanned by (u n0 + v n1) and n2 at speed=a

TransformXRotation2:
Two simultaneous rotations/translations in perpendicular coordinate planes: in the n0-n1 coordinate plane at speed=a; in the n2-n3 coordinate plane at speed=b.

TransformXMoebiusParabolic2:
Moebius parabolic translation in a plane. Computes MatrixExp[u A1 + v A2], where A1 = { {0, 0, -1, 1}, {0, 0, 0, 0}, {1, 0, 0, 0}, {1, 0, 0, 0}}
A2 = { {0, 0, 0, 0}, {0, 0, -1, 1}, {0, 1, 0, 0}, {0, 1, 0, 0}}
TransformXMoebiusParabolic1:
Moebius parabolic translation along a line
Computes MatrixExp[a A], where A = {{0, -1, 1}, {1, 0, 0}, {1, 0, 0}}
Note: matrices are transposed for OpenGL compatibility
