1.3 - Scaling Operations

What's new:

• Ability to display to all outputs with "*"
  • Thanks @mstoeckl ! #26
• Support for outputs with scaling
  • Thanks @y-fujii ! y-fujii@a13273d
• Replaced Wayland protocols xdg_output with wl_output v4
  • This might break unofficial support for non-wlroots based Wayland compositors, such as KWin a5a4750
• Updated GLAD library and Wayland protocols
  • Not required, but it's been 2 years 6b0f7a8
• Some code cleanup and various fixes
  • Thanks @mstoeckl ! #23

Update: I found a fatal race condition 5dcdfc7 when monitors go to sleep, so I updated the release.
