But then you are doing extra work for the "normal" case, and you are
also making the code less readable; not a good trade-off IMO. You
could always move the whole clipping rectangle stuff to avoid the
HeapAlloc (which would also fix a memory leak in the existing code...)
if you prefer. But I think keeping that code readable is more
important than wringing every last nanosecond of the empty clip
rectangle case.
