[vtkusers] OpenGL2 - Broken vtkTexturedButtonRepresentation2D/vtkButtonWidget

[Simon ESNEAULT]

Hello All,

Following our migration to the brand new OpenGL2 backend, the ButtonWidget
seem's broken, the button display's a gray texture instead of an image with
the new backend. This is visible in all our tested platform (Windows or OSX
box)

The following VTK wiki example reproduce the problem :

OpenGL1 backend result :

OpenGL2 backend result :

Is it a known issue ? Any clue ? In our application we try to load a png
image, but it always show a gray/white rectangle instead

Thanks
Simon
