Does not seem to make a difference on my own hardware but for very small 
tiles...
If you build some background with 16x16 tiles (on a 1024 
width-screen->64 tiles per screen ), then the new routine seems a tad 
quicker... I think that maybe we are trying to optimise in the wrong place.

For my purpose I am well conscious that I would be better off writing 
the tiling engine in C and wrapping it later do control it through python.
I am just too lazy yet ;)
