     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.
