Here are a few questions I have specific to Performer's texturing and
coplanar polygons.

I am running with the Performer Version 1.2

1. How can I find out how much Texture Memory is being used and how much
   is still available, under program control.

2. How can I get a Texture to reflect changes to the image array
   specified in the pfTexImage function call in real-time? I have not
   been successful getting the Texture to change after its initial
   creation, even though the image array has changed.

3. Finally, I am seeing coplanar flashing of polygons in the ocean of
   a terrain database. The swapping seems to be ocurring between the
   polygons of the ocean and the Performer earth model. Is this
   possible?

Thanks,
