Is there a function like D3DXVec2TransformCoord() in OpenGL/GLUT? According to MSDN docs:
"This function transforms the vector, pV (x, y, 0, 1), by the matrix, pM, projecting the result back into w=1."
Thanks in advance!

EDIT: I can do the transformation, but I have no idea what they mean with projecting the result back into w=1. :?
