PsychStartup – Perform Psychtoolbox related setup at Matlab/Octave startup.

This performs setup of Matlab or Octave at session startup for
Psychtoolbox.

On MS-Windows, it currently detects if the [GStreamer](GStreamer) 1.22+ runtime is
installed, as this is required for Screen() multi-media functions to
work. It performs [GStreamer](GStreamer) setup, or outputs a warning if the runtime is
missing.

This function is normally called from the startup.m Matlab startup file,
or from the .octaverc startup file on GNU/Octave.
