Remarks
Matrix math utilities. These methods operate on OpenGL ES format matrices and vectors stored in float arrays.
Matrices are 4 x 4 column-vector matrices stored in column-major order:
m[offset + 0] m[offset + 4] m[offset + 8] m[offset + 12]
m[offset + 1] m[offset + 5] m[offset + 9] m[offset + 13]
m[offset + 2] m[offset + 6] m[offset + 10] m[offset + 14]
m[offset + 3] m[offset + 7] m[offset + 11] m[offset + 15]
Vectors are 4 x 1 column vectors stored in order:
v[offset + 0]
v[offset + 1]
v[offset + 2]
v[offset + 3]
