Faster 320x240 graphics

Would the expand() not be a perfect candidate for the now available assembler?

In a way, however as you couldn't allocate a buffer big enough for everything you'd still have to send the pixels in chunks. Having it built-in to 'write' could save that overhead.

Another option that would make the assembler easier is something like E.mapInPlace(to,from,mapFn). Of course if JS had an in-place version of map you wouldn't need any of this either :(
