debugging OpenGL on Windows

Bob,

By default the log should *only* be written if it is enabled through calling

B3DHardwareEngine primitiveSetVerboseLevel: x

which enables debug output from level x= 0 (none whatsoever) to 10 (almost
everything). The default is set to 1 (which means log only critical errors)
but should be set between 3-5 depending on what you're looking at.

If you get the log always then it's likely that its set to a different level
by default on the Mac (I haven't looked at how John handles this). Also, be
warned that on Windows machines the log can show up in really weird places -
if you can, ask your folks to search for it on the hard disk (good guesses
are the user's home directory and the desktop but I've seen it in other places
too). This problem has been fixed with the latest VMs.

Cheers,
  - Andreas
