Dispatches touch events to captured window

Dispatches touch events to captured window

We were doing this before I switched us back to the per window
CaptureClient. We need this since current code assumes SetCapture
captures both mouse and touch events.

This also turned up a bug in CompoundEventFilter. It may end up
showing the cursor on the wrong root, resulting in the cursor
remaining hidden. As we don't need the cursor hiding logic on windows
I'm turning it off for us (windows hides the cursor for us).
