[greatlrd] 25237: commit same strechblt code for 8, 16, 32, it does not using putpixel anylong for 8 and 32, and small cleanup 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.

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