Good idea!

Cool idea too! And it wouldn't be so hard to get it working even with function 
and pattern, I think.

One small thing, with me being the one who likes to break down good ideas ;-): 
Don't forget that I'm still planning to change the getPixel basics a bit in 
the tilemanager, because of the swapping and mmapping. That might need to see 
a few small changes to your plan (like let getPixel not return a pointer, but 
let it also write to a user-preallocated piece of memory). Nothing serious, 
though.
