[vtkusers] Crash in vtkShaderProgram/vtkOpenGLPolyDataMapper

[Ken Martin]

That call stack looks fine to me. As long as it is happening in whatever
Java thread you have setup for Rendering it should be fine. Specifically
that call to CreateAWindow looks like the standard call stack for creating
a window in VTK on Windows. When that call fails to get a pixelformat it is
typically because it is called twice with the same HDC/Window. That will
return zero on windows.

Maybe somehow the same canvas (or whatever the java thing is called) is
being used when creating two RenderWindows, or creating one, destroying and
creating again. Somehow I would bet the same windows window/HDC is being
used twice for two different RenderWindows.
