I wrote a little program that animates a dinosaur running across
the screen. The problem is that sometimes it crashes with the
guru #81000009 freeing memory already freed. If I remove one
of my calls to BltPattern then the problem appears to go away.
I looked at the documentation for this call in the RKM but it
has a very terse description. My question is: does BltPattern
clip to the destination or do I have to do this myself?
