[vlc-devel] [PATCH 16/16] vout: win32: handle 360 user-interaction

[Thomas Guillem]

These changes make sure that we handle mouse-dragging inside win32 for
projection modes that are not RECTANGULAR. We will swallow events that are to
be interpreted as viewpoint-change-requests, while making sure that others are
propagated to the core so that others can react to them.
