[winswitch] scaling issue on iMac

[Cameron Taggart]

I got rid of the "--no-install-recommends" in the install, and now the
install of xpra 0.17.2 is as recommended.

The issue is that it is zoomed in too much by default. I posted a
side-by-side screenshot as well as the server and client output here:

Any suggestions on how I can fix this manual or automatically would be
awesome. I want to show off Xpra to others, but need to fix this first.

cheers,
Cameron
