Actually, this is what "client draw" was supposed to be about.
However, there is as showstopper (see Announcment): "client style draw" requires fast memory->VGA transfer and while that works fine on most HW, some machines produce very low numbers.
So while the original plan was to replace all drawing operations with memory-based ones (and allow anti-grain support etc), this now seems impossible as long as we have to support older machines (and at least I have to: some of my clients are still sometimes using 233Mhz/64MB/Win98 HW).
That in turn means that instead of "default", "anti-grain" will be supported just as an option to draw in Images.
That still means Draw needs and Image needs huge refactoring. I hope it will happen soon (must happen before WinCE / MacOS / Chameleon)
