> We can also examine what happens when we write data repeatedly. I wonder whether an optimizing compiler can detect and optimize the sequential writes of the same values, possibly by replacing them with something like a blitter. It would be interesting to see the difference in speed if the data to be written was random, rather than the same value (1.0) every time.
