[winswitch] [ANNOUNCE] Xpra 3.0.3: many fixes, some important

[Antoine Martin]

Hi,

This update fixes quite a few bugs, in particular:

* The OpenGL paint issues should finally be fixed correctly on all
platforms, with all Python / GTK combinations.

* Other window painting issues: GDK scaling compatibility, slow
repaints, HTML5 video, etc

* Many MacOS fixes: dialog focus, remote start via ssh,
fullscreen/maximized windows, window resizing, etc

* Installer errors on MS Windows

* Library updates and compatibility fixes, ie: Python2 vs Python3
regressions

And much more. Updating is recommended.
