Well, doesn't mmap return memory that is aligned to the page size, so will 
probably be aligned there in any case? Then rests both the memory pools 
(align the first tile, and all the following ones should be aligned as well) 
and the fallback new Q_UINT8 call if there is no pool. That last probably 
needs some more care, but I guess no big changes would be needed at all.
