[Coco] OS9 / Nitros9 - Getting direct access to graphics memory.

Walter, yes, you can map the graphics memory into the workspace. It's a little tedious, but doable. You can map it in with 8k blocks (using less memory) or the complete graphics memory.
I do this very thing in MShell to do direct drawing for speed.
PM me and I'll give you the steps to do it.

Is there an OS9 call to map the graphics memory into the process space?
