Removed unused code from HMinimenuItem
HMiniMenu bug fixes.
Bug fix: Update flexible rect dimensions after animation
Add scrollTop/Left from document.body instead of document.documentElement, which may have worked in the past, but doesn't work anymore.
_getVisiblePosition (used by pageX and pageY of views/controls) doesn't add double scroll position anymore, as the root of the problem (the event x/y) works now.
Event management overhaul; got finally rid of mouseover/mouseout events for focus/blur triggering.
