ALL scrollbars are not working correctly with mouse dragging. Only mouse
wheel will work. This is because the implementation of the scrollbars in
the lcl is not completed. Scrollbars are not automatically affecting the
client rectangle and send mouse events with their own coordinates. That's
the reason why no component can decide if the mouse event is from scrollbar
or not.

This is because of some inconsistency in the lcl gtk interfaces. Some
components produce mouse coordinates with different origins. This was not
critical before. But the designer depends on complete consistency.
Therefore this is not one bug but many little ones. Hopefully they will be
fixed in the next few weeks.

Witty test. :)
I have found the bug. (There were two.)
