New Revision: 946

Log:
Add another "reuse" permission, to distinguish between the case where a
source filter will simply want to re-output the same image multiple times
and reuse a buffer to do it, and the case where the source filter will
output multiple image by modifying a single buffer and outputting it multiple
times.
