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
