New features and improvements:

• SetMouse multi-screen improvements for Windows. Allow positioning relative to screen origin, as the screenNumber is now also honored on Windows.
• CMUBox doc updates for Windows. Describe how FIFO size must be set on Windows COM ports for good timing.
• KbQueue fixes for OSX. Avoid hang of scripts in KbQueueRelease on some OSX setups.
• PsychPortAudio improvement for Linux. Try to avoid selecting HDMI/DP audio on video outputs of graphics cards as default sound card. Prefer regular sound cards over graphics cards with sound output if possible.
• Handle Intel ddx DRI2 triple-buffering on Linux, so visual timing works on Intel graphics chips without need for special xorg.conf settings or ddx drivers. It is now possible to even take advantage of triple-buffering with properly adapted scripts.
• General improvements to timing checks on advanced operating systems which support OS native timestamping mode 4.
• Documentation updates.
• Fixes and refinements to demos.
• New function CenterRectArrayOnPoint() contributed by Natalia Zaretskaya.
• QuestQuantile() improvements by Denis Pelli.
• Some improvements to color calibration routines by David Brainard.
• Improvements for efficiency of clut updates and of error handling on VPixx devices.
• Some compatibility updates to joystick configuration files for current Linux distributions.
