opengl: use MVP matrix in vertex shaders, pixel offsets
ChangChange all vertex shaders to accept model, view, projection
matrix to calculate the vertex position. So now we don't need to
convert the coordinates to OpenGL coordinate space [-1.0, 1.0]
anymore.
Additionally make it possible to offset vertex coordinates so
we can apply 0.5 px offset (to hit the pixel center) at some
operations.
