Yes, I was wondering about the timing results earlier - that's why I put the complicated timing code inside pink.c. And still, it didn't change anything. The following program has maybe something to do with it:
In about 50% of the runs it reports about 2000 blits/second, in the other 50% it reports about 4000 blits/second. I have 3 explanations so far: Some mistake I made in the code, some memory alignment issue, something with the clock() function.
