gldrawcontext_fbo_new requires that the OpenGL version is 1.2 or later, 
and GL_EXT_framebuffer_object.

I'm not sure I understand you... you called Q3View_GetDrawContext on a 
view that has been rendered?

If I understand correctly, since you cannot debug Quesa, you are adding 
logging statements to Quesa.  I suggest that you add a log statement to 
GLDrawContext_New where kQ3DrawContextPropertyGLContext is set, and 
write out the value of theDrawContext.  Also write out the value of 
masterDrawContext in gldrawcontext_fbo_new.
