Convert a homography matrix to a gl 4x4 matrix to apply the homography to a gl texture
/* calculate a new homography matrix if the src or dst quads have changed */
if(x->changed)
{
// cvFindHomography(x,x,x); // can also use this, it is supposedly more accurate, but requires some unnessesary copies and i didn't see a difference
cvWarpPerspectiveQMatrix( x->cvsrc, x->cvdst, x->homographyMatrix ); // calculate homography
x->changed = 0;
}
// output the transformation matrix (format it as a 4x4 matrix that works with opengl)
