Mac OS X：CGGetLastMouseDelta并以编程方式移动鼠标

I'm developing an extension to MATLAB's PsychToolbox that allows for better control of the mouse during psychophysical experiments (specifically, preventing the screen boundaries from limiting drag operations... it should feel like you can move the mouse "infinitely" in all directions). Since MATLAB doesn't support the creation of additional threads (and that would be needlessly complicated for this situation anyway), I can't make use of either the Carbon or Cocoa event managers.I'm developing an extension to MATLAB's PsychTo
