Const iterators, what's next ?

[Boudewijn Rempt]

I would prefer distinguishing the factory methods for iterators iterators by 
name, not just by their intrinsic constness: much easier to read.

As for the parameters of the filters: I tried ditching dst (since having a dst 
without a src doesn't make sense) but failed. I have forgotten why, though. 
Just one thought: wouldn't it make more sense to have an iterator as a 
parameter instead of a whole paint device? More c-plusplussy? Of course, that 
would mean that all iterators need to be constrained to a rect, not just the 
rect iterators. I'm not sure that this is a good idea, but there must be a 
reason stl doesn't pass the whole array & a range but iterators instead to 
its algorithms.
