/*
* TODO
* + provide a UI for configuring optional parameters, but keep cmd line args
* + audio redirection is delayed considerably
* + caps lock key needs to be sent in func flagsChanged()
* + libfreerdp-utils.1.0.dylib needs to be installed to /usr/local/lib
*
* - MRDPView implementation is incomplete
* - all variables should have consistent nameing scheme - camel case
* - all funcs same as above
* - PolygonSc seems to create a transparent rect
* - ensure mouse cursor changes are working ok after moving to NSTracking area
* - RAIL:
* -
* -
* - tool tips to be correctly positioned
* - dragging is slightly of
* - resize after dragging not working
* - dragging app from macbook to monitor gives exec/access err
* - unable to drag rect out of monitor boundaries
