Yes, the first patch was not working, but the second patch is ok, and the
texture is correctly rendered !
Thanks a lot, will this patch be merged in the VTK 6.3.1 release ?

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 :

http://www.vtk.org/Wiki/VTK/Examples/Cxx/Widgets/TexturedButtonWidget



OpenGL1 backend result :
http://picpaste.com/pics/OGL1_1.1445968197.png

OpenGL2 backend result :
http://picpaste.com/pics/OGL2_1.1445968221.png


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
