Caused by rB5b34d11b55e0.
Above commit restored the view matrices in ED_view3d_draw_offscreen
_before_ they can be stored in the ImBuff (see ED_view3d_draw_offscreen
/ texture_paint_image_from_view_exec).
Now make restoring the view matrices optional and dont do this in case
of reprojection, so the used matrices can still be saved in the ImBuff
later.
