30 * It looks like cairo_show_surface has no effect if it follows a
31 * call to cairo_move_to to any coordinate other than 0,0. A little
32 * bit of poking around suggests this isn't a regression, (at least
33 * not since the last pixman snapshot).

39 * Inside cairo_show_surface the current point was being used as
40 * both source and destination offsets. After fixing that to use 0,0
41 * as the source offset and the current point as the destination
42 * offset, the bug seems to be gone.
