Build silently fails on Windows

cpml.mat4.to_vec4s() and cpml.mat4.to_vec4s_cols() are reversed

CPML documentation states that cpml matrices are column-major. ```lua local testmatrix = cpml.mat4.new{1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16} ``` This...

cpml.mat4.from_transform() computes the wrong rotation matrix.

cpml/modules/mat4.lua: ```lua local rx, ry, rz, rw = rot.x, rot.y, rot.z, rot.w local rm = new { 1-2*(ry*ry+rz*rz), 2*(rx*ry-rz*rw), 2*(rx*rz+ry*rw), 0, 2*(rx*ry+rz*rw), 1-2*(rx*rx+rz*rz), 2*(ry*rz-rx*rw), 0, 2*(rx*rz-ry*rw), 2*(ry*rz+rx*rw), 1-2*(rx*rx+ry*ry), 0, 0,...

Please add a `cpml.mat4.decompose()` function that will decompose a matrix into its Vector3 scale, Quaternion rotation, and Vector3 translation components.
