Summary: optionally disable direct rendering at runtime

Initial Comment:
I think it might be useful to be able to choose at runtime to use direct rendering (ie, GPU hardware acceleration) or not (ie, CPU software rendering).

Rationale: GPUs are very fast, but transfering images back to the CPU is very slow. When rendering "offline" (eg with pix_write) it might turn out to be faster overall to use software rendering than direct rendering, depending of course on scene complexity.

I don't know if it is possible to implement, but I guess the user interface would take the form of a message to [gemwin] before the "create" message.
