Using Windows 10, 64 bit, The report mouse shape changes and enable mouse tracking options checked. NVDA is not announcing the shape change as the mouse pointer is moved. I don't know if this applies to any other variant of Windows, though.
#3801 (NVDA 2014.2): mouseHandler only reports the shape after it is pumped 10 times to avoid flooding. However, we no longer pump constantly, only on demand. This needs to be changed to a timer instead.
#5302 (NVDA 2015.4): We seem to be missing most cursor shape changes. I'm pretty sure this is because these get blocked by eventHandler.shouldAcceptEvent. The fix is probably to allow events from the desktop window.
* Cursor events end up firing on the desktop window, so shouldAcceptEvent had to be taught this.
* The previous code relied on counting core ticks, but now that core ticks are on-demand, this needed to be updated to use a timer.
