Subject: [PATCH] Hacks for testing cursor control by server for a leased out
 drm/randr output.

- Allow enable of atomic modesetting under modesetting-ddx to test how
  an atomic server would behave.

- Disable some checks to allow X-Server to control cursor appearance and

function BasicSoundPhaseShiftDemoPimped(showit, targetChannel)
% BasicSoundPhaseShiftDemoPimped([showit=1][, targetChannel=1])
%
% Demonstrates how one can play back a phase-shifted sine tone, with dynamically
% adjustable phase shift, free of audible artifacts during phase shift change.
%
% This uses PsychPortAudio's realtime mixing and some trigonometric math to
% synthesize a cosine wave of selectable phase in realtime from the weighted sum
% of a pair of a cosine + sine wave with different relative amplitudes.
