I think it should help Bart in that it gives a cleaner, but doesn't this still
mean that you need to create a temporary target paint device? That's the big
problem. Of course, if we could invent something like a 'lazy' paint device
that only allocates tiles if and when and where pixels ares changed, that
should help enormously. That's more or less what Casper was doing with the
autoextending layers, isn't it?
