r16604 adds a test application (very slow to run..), which looks like this on Linux (with or without xpra):
The right hand side shows the difference between the antialias setting shown on the left and the "NONE" setting.
So far it shows that I am unable to force sub-pixel rendering to turn on, only gray (which is the default is seems).
Interestingly, it does enable sub-pixel rendering on MS Windows where the colours are clearly visible on the deltas:

RGB sub-pixel order which is correct. (this inverted since we XOR the two images!)
And this is confirmed by the value retrieved through the API, see
