Follow up from #1358#comment:5, enhance the GL check code to create a temporary window with textures and go through one fake paint call to verify that the opengl driver is usable.

Done in r15007:

• greylisted chipsets are now enabled, you will see a warning similar to this one:

Warning: vendor 'NVIDIA Corporation' is greylisted,
 you may want to turn off OpenGL if you encounter bugs

• we test rendering using a hidden temporary opengl window
• the errors from Seeing opengl errors when forcing opengl=on with Intel 4000 video card #1358 are no longer ignored, and should cause the rendering test to fail with a message similar to this one:

OpenGL test rendering failed:
 OpenGL RGBX paint error: GLError(
 	err = 1281,
 	description = 'invalid value',
 	baseOperation = glClear,
 	cArguments = (116384,)
 )

And opengl should be disabled on those broken chipsets.

Works as well as can be expected, next step will be opengl in python3: #1569
