I Have been considering the problem with editing text and drawing editable graphics to an Image. I believe the approach I am going to take is to implement a layer drawing system, I just need to work out the transparency implementation, I know transparancy doesn't truly exist, even at the system level. but I believe it can be faked well. then I know I can save my layered image as a composite. Does this all sound like a good approach??? please any help???
