[Lazarus] TDateEdit vs TDateTimePicker

[Graeme Geldenhuys]

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.

It's clear from TCustomScrollBar.DoScroll that it's unrelated to
LargeChange and SmallChange.

Can the resolution of this increment be set independently of PageSize?

Thx, Bruce.
