Can't track mouse movement if hardware cursor hidden

When I use Canvas.hideCursor() to hide the hardware cursor I lose the ability to track the mouse position. The cause of the issue seems to be twofold:

guiCanvas.cc -- GuiCanvas::processInputEvent()

else if(event->deviceType == MouseDeviceType && cursorON)

So if cursorON is false, we don't process mouse events...

And in GuiCanvas::setCursorON ()

if(!cursorON)
   mMouseControl = NULL;

If cursorON is false, we trash the mouseControl.

Removing those bits solves the mouse tracking issue, but leads to another problem that is likely Mac-specific. When the cursor is hidden and we click the mouse, the Carbon Event Handler thinks the cursor is still where it was when we first hid the mouse. So if you happen to be using a custom cursor, it then teleports it back to that position.

At least in my case I can step around that issue since I keep track of the cursor position myself, and when I get a gameWindow2D::onMouseDown event I just call gameWindow2D.setMousePosition($lastMousePos) and it solves my problem. I don't see a general solution at the moment though.
