Q: Can I clear the z-buffer between QARenderStart and QARenderEnd?

A: If a z-buffer is present, it will be initialized to 1.0 when QARenderStart is called. There is no way to explicitly initialize the z-buffer, although you can usually fake it by setting the z function to kQAZFunction_True and rendering a transparent polygon over the entire context.
