Subject: [PATCH] * modules/gui/macosx/vout.m:   Reworked the mouse hiding
 routine. we were always hiding the mousecursor   on kCGDirectMainDisplay, but
 this display is always the one with the   menubar and not always the one
 containing our VLCVout.   This new code takes the vout, and calculates on
 which displays (plural   because of possible mirroring) it is being shown. It
 then shows or hides   the cursor on all of those displays.   This should fix
 #396.
