  > Fix segv for clipped movie window
  > When playing a movie that is clipped on its left and right edges the
  > Xorg server will SEGV sometimes. This is because the intel driver
  > ignores the clipping info when it copies the planes out of the XV
  > data.  The check for the optimised copy was wrong to ignore the
  > width required.  Which leads to too much data being copied by the
  > memcpy. It the source buffe happens to end exactly on a page
  > boundary the server will SEGV.
  > As we reviewed the code we checked the calculation of src1, src2 and
  > src3.  The patch includes additional comments to make it clear what
  > the elements of the calculation are.
  > This bug exists in git head and we also see it in 2.4.1. (oga@)
