[PD] problem with glsl shaders and texunits

[cyrille henry]

after a very quick look, i noticied that it work if you connect the right output of the framebuffer to the right input of the 2nd texture, in order to set the coordinate.

i thought that Iohannes had recently made some change in order to improve this, but this patch is not working better than before.
maybe because the texture is use not the texunit 0???
