Now one more related question: if the driver (stack) can only scale down,
and the user has requested either a crop smaller than current fmt, or fmt
larger than current crop. What should the driver do? I can think of at
least two reasonably logical behaviours:
1. adjust the last invalid request - either enlarge crop or reduce fmt
2. give fmt preference and adjust the source rectangle if needed
Which one is prererred?
Thanks
