[vtkusers] Rendering fonts crashes OpenGL driver

[Goodwin Lawlor]

Hi All,

I've narrowed down the crashes with vtkActor2D to rendering fonts. The
behaviour is strange: 20pt Arial and smaller crashes the OpenGL driver.
Courier and Times are OK at any size font. Rendering "-" in any font family
at 20pt and smaller crashes...

Could anyone take a guess at what's going on? Does the vtk text mapper
depend on system fonts? It doesn't seems so. Could the fonts be corrupted!?
Or a bad OpenGL driver.

Setup:
Dell Inspiron 8600
ATI Mobility Radeon 9600 Pro Turbo
Windows XP
Latest CVS of vtk

Thanks,

Goodwin
