Summary0004615: VTK OpenGL2 Backend: Warnings about error in cache state for GL_SCISSOR_TEST
Description

When Slicer is built in debug mode then any render operation (even just rotating the empty box in 3D viewer) generates a long warning message.

<pre>
Generic Warning: In C:\D\S4D\VTKv9\Rendering\OpenGL2\vtkOpenGLState.cxx, line 138
Error in cache state for GL_SCISSOR_TEST

It seems that VTK and Qt's states are temporarily get out of sync and this generates the warning.

Calling ostate->vtkglDisable before f->glDisable in QVTKOpenGLNativeWidget::paintGL() (around Line 532) seems to fix the issue:

Current (generates warning):

f->glDisable(GL_SCISSOR_TEST); // Scissor affects glBindFramebuffer.
ostate->vtkglDisable(GL_SCISSOR_TEST); // Scissor affects glBindFramebuffer.

Updated (does not generate warning):

ostate->vtkglDisable(GL_SCISSOR_TEST); // Scissor affects glBindFramebuffer.
f->glDisable(GL_SCISSOR_TEST); // Scissor affects glBindFramebuffer.

I was just playing around with this, so I'm not sure that this is a proper solution but it seems to work.

I think this was fixed in VTK master. See https://github.com/Kitware/VTK/commit/60989d5e79bd25154e7c2416d47843ec1536de0d#diff-6e5f5332237272bf7cf332e80ffcfb36

Great, thanks, then we just have to update VTK in Slicer!
