...this is easy:  it's not working because the gemwindow creation  
doesn't request a stencil buffer (at least on osx and linux)!   
However, I just committed a small change to the osx code that indeed  
does enable the stencil buffer, and it should be just as easy to do  
for linux and windows...after doing so, the patch works as expected...

...this does bring up an issue:  should we always create the  
additional buffers (ie. depth, stencil, accumulation, aux), or should  
we create a message for gemwin to selectively enable/disable these  
before window creation?  Currently on osx, 24bit depth and 8bit  
stencil buffers are created, and on linux it just creates a 16bit  
depth buffer...

time to go out,
