Fix a pause in the event loop when clicking the title bar on windows (#4136)

* Fix a pause in the event loop when clicking the title bar on windows

When clicking the title bar on Windows, to drag the window, there is
a noticible pause in continuous redraw requests. This was fixed
in #839 and then regressed in #1852. The cursor blinks in both
cases and is unrelated. The regression made the blink happen after
the pause instead of immediately.

* Update the event loop pause note on the WM_NCLBUTTONDOWN handler

The application example was also updated to optionally animate the fill color
in order to demonstrate continuous redraw without pauses in the event
loop.
