QA:Testcase radeon 3D pymol

Description

A basic rendering check using the PyMol molecular viewer. You must be using a card supported by the Radeon video driver.

How to test

1. Ensure the 'nomodeset' kernel parameter is not enabled in your bootloader configuration (unless you need it for basic X operation to suceed)
2. Ensure that

glxinfo <pipe> grep 'OpenGL renderer'

does not return 'OpenGL renderer string: Software Rasterizer'

1. Install the pymol package: yum -y install pymol
2. Launch PyMol from a terminal
3. Go to Wizard => Demo => Representations. There should be a list of demoes on the right side of the Pymol viewer window.
4. Click on each demo in turn. For each demo:
   1. Use the mouse wheel to increase or decrease complexity
   2. left-click+mouse to rotate
   3. middle-click+mouse to move around
   4. and right-click+mouse to zoom in/out
5. Quit pymol.

Expected Results

1. all the demoes should run without crashing
2. there should not be any obvious misrenderings (flickering, surfaces that come and go...)
