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.

Also improve documentation, and deprecate the old broken functions.

The configuration system cannot store both a static list and a dynamic
one (and AFAIK, it never could). It only makes to use either a static
list or a callback.
