[winswitch] xpra v0.17.6 multiple Ubuntu 16.x systems, cursor in shadow mode

[Stephen RoundSparrow]

Hello. Congrats on the pending 1.0 LTS release. The feature list looks
great.

In shadow mode I've been unable to get the cursor to work. Resizing
cursors, edit cursors, etc just don't appear and it is always an arrow on
the client system.

I have an Ubuntu 16.04 client that I updated from xpra v0.15.8 to the
latest xpra v0.17.6 off the ppa. One host is Ubuntu 16.10 with it's xpra
v0.17.4 and another is Ubuntu 16.04 with it's xpra v0.15.8 version.  I've
tried adding --cursors=yes to client and it shows enabled on the Info
screen but neither host system will pass cursor changes to the client.

Is cursor mirroring in shadow mode unsupported or some other thing to try?

Thank you.
