Xpra: Ticket #1367: enable more opengl chipsets

Follow up from ticket: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.

owner changed from Antoine Martin to alas

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 #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.

Intel driver woes continue: ticket:1469#comment:14.

Mon, 10 Jul 2017 14:44:05 GMT - Antoine Martin: status changed; resolution set

status changed from new to closed
resolution set to fixed

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