observing vram usage

[Keith W. <kw...@cs...>]

Say I want to known how much VRAM is necessary for a program I've written,
or conversely that I want to write a program and generate models and
textures for use in the program such that I know it will require no more
than some specified amount of VRAM.  Either of these two opposing
scenarios is possible and useful of course.

Are there any function calls that reveal this kind of information to me?
I can get a clear indication of how often the computer is swapping models
and textures in and out of VRAM, or whether VRAM is even full in the first
place at any given point in time?

Thanks.
