Qt ensures event IDs are never reused by providing a way to register
them dynamically. We have code that allocate event IDs statically and we
need to check/register those then to ensure proper offset for dynamic
ones. (we could just register them too, but this wouldn't allow
switch/case through values)

Pointed out that LeafToParent_Type was misused.

Some events are fired on each meta type detection, while we just handle
those events on a global change basis.
Qt has some similar deduplication for repaint() or touch events, but
does not provide it to user.
