You can keep the 24bpp window as it is. 24bpp is slow enough - I don't think 
unaligned memory access will count for much :)

Also here's another suggestion: for memory BITMAPs, the line pointers can 
also be aligned on 8 byte boundaries. This will give a significant speed 
boost on Intel CPUs. Of couse, it'll break every program that uses the 'dat' 
 or line[0] fields instead of line[n].
