commit same strechblt code for 8,16,32, it does not using putpixel anylong for 8 and 32, and small cleanup

Browse source 
this code can be makefaster, how remove getpixel that will doing huge incress in speed, split calc to
simple 1x 2x .. zoom in/out now we are using 1.1x 2.2x Zoom and 1x 2x zoom same code. if we split it we will
see a speed incress.
