++ - Added Vulkan support.

++ - The QPA plugin now supports running with no screens attached. This is
++ handled by adding a fake screen when the last screen is disconnected,
++ similarly to what the other QPA plugins do.
++ - Added support for drawing tablets through the tablet-unstable-v2
++ protocol.
++ - xdg-output-unstable-v1 version 3 is now supported.
++ - Windows with Qt::FramelessWindowHint no longer create
++ zxdg_toplevel_decoration_v1, as that allowed compositors to force
++ server-side decorations.
++ - The QPA plugin will now use the same platform themes as the xcb plugin.
++ - Fixed a bug in font gamma correction making text appear too dark.
