/* Bug history
*
* 2004-10-25 Carl Worth <cworth@cworth.org>
*
* It looks like cairo_show_surface has no effect if it follows a
* call to cairo_move_to to any coordinate other than 0,0. A little
* bit of poking around suggests this isn't a regression, (at least
* not since the last pixman snapshot).
*
* 2005-04-02 Carl Worth <cworth@cworth.org>
*
* Status: RESOLVED
*
* Inside cairo_show_surface the current point was being used as
* both source and destination offsets. After fixing that to use 0,0
* as the source offset and the current point as the destination
* offset, the bug seems to be gone.
