Xpra: Ticket #1155: synchronize client colourspace / calibration
This may impact #1107 (containers can specify the colourspace used for rendering), #41 (not sure how to handle this one..)
We want to capture the colour profile that the client will use for rendering our pixels on screen(s) and expose it to the server so applications will use it, and / or ensure we use this profile when encoding the pixels.
MS Windows specific info:
As per the arch wiki, a number of apps already use the icc profile: firefox, eog, gimp, mpv, ..
Here's how I set my icc profile:

- r12282 + r12292 adds basic ICC information for win32 collected using pillow which calls
GetICMProfile - we could pass it an HDC for each monitor to get per-monitor information, but this would need to go with changes to ensure that the monitor indexes used for reporting the geometry are the ones used for icc (GTK messes with things and may re-order monitors...)
- r12284 does the same for OSX, where we get per-monitor values too (same monitor-order caveat applies) - here, we do get the raw ICC data in a blob already, so this can easily be applied server-side
- for Linux, I think we need to make sure python-pillow is built with lcms support - and even then, I don't get any values out.. but I do get lots of data using

Time to collect some data, at least on OSX and win32.
Then we can decide what to do with it.
Lots of work done on this: OSX clients colourspace detection, ICC profile export to the session - ticket:1086#comment:4

I don't have the hardware required for testing this, re-scheduling.

I'm not alone in thinking that colour management on Linux is a mess: Open Source Color Management is broken
