start of new strechblt huge speed incress, the idea is not doing any mul or the div in the for loop. this is only done for 16bpp, same code will be copy to rest later.
1. remove all div and mul from for Y loops 2. todo remove so much as psoible mul and div from X loop svn path=/trunk/; revision=25202
