Subject: Add minimalegl QPA platform plugin
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The EGLFS platform plugin was originally meant to be an example
and thus to be kept simple. However, EGLFS is becoming more
and more complex with the addition of hooks for board support,
cursor integration, built-in evdev support etc.

minimalegl is a new platform plugin that intends to follow
the original intentions of EGLFS.

The code is an adaptation of EGLFS as of f913859f8
