The mail was down here last night so I don't think this got out.  Let me
try again.

Subject: [video] bktr clipping

     Started trying out the bktr clipping half hour ago and noticed a few
small bugs.  My tests have been very minimal, but so far what I've noticed
is that the driver seems to swap X and Y (X and Y defined per display
convention and as X does), and the Y coordinates (X, with the swap bug) are
doubled when capturing both fields.  The latter's probably just a loop
stepping typo.

     For example, with this clip rect:

     (X 10, Y 50) - ( X  20, Y 100 )

with single field, what gets clipped is:

     (X 50, Y 10) - ( X 100, Y  20 )

and with double field, it's:

     (X 50, Y 20) - ( X 100, Y  40 )

Will continue working with it tomorrow ev.  BTW, this is with the 971005
driver off of rah.

Thanks,

Randall
