[PATCH] nv50/gallium: small fix for nv50_transfer_rect_m2mf (sy <-> dy)
...emains unchanged).
Now one could do
so_data (so, fui(-(nv50->viewport.translate[1] - nv50->framebuffer.height));
as well, which would make the viewport transformation correct, but the ST still
outputs the wrong vertex coordinates for clear_with_quad.
To fix both things, one could just let st_fb_orientation in st_context.h return
Y_0_BOTTOM, but then glCopyTexSubImage2D (calling the appropriate function in
st_cb_texture.c) flips the image and copies from the wrong offset, since offset
0 in memory is, well, top, as opposed to bottom like it seems to be for vertex
coordinates that bypass the viewport ....
