Async Drag Window 1.0

AsyncDragWindow is a window subclass that allows you to drag windows without blocking the rest of your application. Timers and threads will execute, and content in all windows will continue to update throughout the drag.

This behaviour is achieved by using the kWindowAsyncDragAttribute flag introduced in Mac OS X 10.3, therefore this class requires 10.3 or higher for full functionality. It should function in 10.2 as well, but drags will block as usual in that case.

NOTE: Properly supporting asynchronous dragging required that the Window class Moved event, and Left/Top properties be re-implemented. The end result is the same as an unmodified RB Window however, and existing code should continue to work as-is. If you notice any discrepancies please email a bug report.
