Mirror a sprite

Another (memory expensive) faster way to reverse the bit in a byte is to have a table:
[0] -> [0]
[1] -> [BIN 10000000]
[2] -> [BIN 01000000]
.. and so on
but yet again you still have to reverse the byte order (this can be done in the routine if it reads the bytes in reverse order in memory)

As I said in the last post

Certainly! sorry, I overlooked it.
BTW glad to see you alive and kicking. I'm working *very* hard in the new ZX Basic version, unfortunately I won't reach tomorrows deadline
I have some improvements pending to include your libraries and some Fast floating point one.
