[Qt-interest] QGLFormat missing capabilities

I need to specify QGLWidget capabilities beyond the ones supported in 
QGLFormat. 
Does anyone know a way of specifying GL capabilities that are not 
explicitly supported in the QGLFormat class?

The immediate problem is that QT 3.3.8  is not enabling the GL AUX 
buffers on MAC OSX 10.5.6, using the X11 version of QT, even though 
there are AUX buffers in the graphics card.  This does not appear to be 
supported in QT 4 either. 
You can enable the buffers in glut (using glutInitDisplayString()), but 
I can't find any way to tell QT about gl window capabilities other than 
depth, double buffer, stereo, accum, etc, (using QGLFormat).  As a 
result, I can't use the aux buffers in QT.
Thanks for any ideas on this!
