Of course test2 would be faster.... but you're only talking about system memory
& putpixel - what if you were talking a screen... that may be linear... may be
planar... may be bank switching...?

Flexibility sometimes does have a price... it's up to you where you might want
to work AROUND something Allegro does... rather than WITH  it...
