In what order does OpenGL ES 2.0 read the elements of a matrix?

Question

I'm confused. Is it:

0 ,1 , 2, 3 4 ,5 , 6, 7 8 ,9 ,10,11 12,13,14,15

or something else?

OpenGL matrix order is column major:

0, 4, 8, 12 1, 5, 9, 13 2, 6, 10, 14 3, 7, 11, 15

There is a set of functions to load, multiply, ... line major matrices: glLoadTransposeMatrix.

Those functions don't work under ES 2.0. You have to do it all manually. But thanks for the byte order!
