Author: Henri Verbeet <[email protected]> Date: Fri Dec 14 04:14:14 2012 +0100 gallium/u_blitter: Remove the overlapped blit assert from util_blitter_blit_generic(). This is used by st_BlitFramebuffer() / r600_blit(), and ARB_fbo allows overlapped blits, even though the result is undefined. No piglit regressions on r600g / CYPRESS.
