Summary:                    vtkTextActor disappears when there is a vtkActor
with BackfaceCullingOn
Description: 
When there is a vtkActor with BackfaceCullingOn drawn just before a vtkTextActor
than the vtkTextActor disappears.

This due to GL_CULL_FACE state is leaked (set in vtkProperty::Render) to the
next vtkTextActor render state.

See the attached example. When you press 'n' which changes the culling setting
of the 2nd sphere, the text disappears. 'b' changes the culling of the first
sphere.
