anyone else than Bill got any comments?
Would you agree with Bill that 0x0 source rect should not be legal?
Or if we should raise an error on negative sizes rather than just take
it as "disable"?
I am indifferent on these two questions, so if no-one voices their
support for these minor changes, I won't bother.
