How would you determine if a file exists? The docs list
#fopen/read/write/fclose, but not any other file IO functions. Is this
possible with POVRay?

From "3.2.2.3.1 The #fopen Directive": You may use #ifdef
FILE_HANDLE_IDENTIFIER to see if a file is open.
So I think using #fopen to open the file, and then using #ifdef on the file
handle identifier will check if the file exists.
