Subject: [PATCH 08/16] libobs: Introduce the concept of a Unix platform
This is a Unix-specific code. The only available platforms
at this point are the X11/GLX and X11/EGL platforms.
The concept of a platform display is also introduced. Again,
the only display that is set right now is the X11 display.
