Subject: cocoa: fix mouse hiding with launchpad and dock folders
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Some UI elements in OS X – like Launchpad and Dock folders – are implemented
using borderless windows in background demonized applications.
When we use these elements, mpv doesn't stop to be the active application, but
the mpv window leaves keyWindow state while we use the OS controls.

This commit just keeps track of window state to update the cursor visibility
accordingly.

Fixes #513

(cherry picked from commit ce239f1577ccd7eabccaac5b3b34fbe3959d860e)
