I have been having some trouble getting the BltBitMap() function to work
properly.  I am trying to do a simple copy from one bitmap to another
of the same size (both allocated in ChipRam).  The function returns 0,
which means that it hasn't copied any of the bitplanes.  The following
code should illustrate what I'm trying to do.  

struct BitMap *bitmap1, *oldbitmap1;
struct ViewPort vp1;
WORD blitnum;

....

blitnum = BltBitMap(bitmap1, 0, 0, oldbitmap1, 0, 0, vp1->DWidth, vp1->DHeight,
		0xc0, 0xff, NULL);
....

I have also tried this with a TempA allocated.  I have also inserted a
WaitBlit() and OwnBlitter(), DisownBlitter().  I must be making some blaring
error somewhere.  All I want to do is copy a full bitmap, nothing fancy.
Any suggestions or pointers :-) will be greatly appreciated.  Thanks in
Advance.
