When the mouse wheel is used to change the position of a TScrollBar,
what determines the size of the increment?
Empirically it appears to be related to the PageSize property but not in
an obvious way.
Some time ago I've used a dual definition for the mouse wheel scroll:
positive values indicate an item count (items=lines...), and negative
values mean fractions of the page (window) size, e.g. -3 means 1/3 page.
Such a convention could e.g. replace and extend the SynEdit half-page
scroll option.
