[vtkusers] Rendering problem on OSX

[Yves Starreveld]

Hopefully someone with OpenGL knowledge can provide some insight...

<http://www.vtk.org/Testing/Sites/atamai.irus.robarts.ca/Darwin-6.1- 
c++/20020930-0300-Nightly/Results/__Rendering_Testing_Tcl_ScalarBar- 
image.html>

Shows the output of a test on OSX. The text (from  
vtkOpenGLFreeTypeTextMapper) is being _partially_ overwritten by  
portions of the sphere. I wonder if this may be a driver-specific  
problem, (ATI Radeon) since it has started happening since the  
10.1-10.2 update. (anyone with a GeForce machine to test on?)

Any pointers appreciated.
