that doesn't make much sense to me... when you re-assign the global
pointer inside the fuctions you're losing what it was previously
pointing to... so unless you have something like:
BITMAP *tmp = da_bmp;
da_bmp = create_bitmap(...)
...
destroy_bitamp(da_bmp);
da_bmp = tmp;
or destroy the bitmap before you reassign it... you're going to have
unfreed memory. which I don't think would give actually errors...
except in memory leaks... but what do I know?
