Subject: [PATCH 359/398] vcl lok: handle tracking coordinates which are in
 twips

This is similar to the mouse button down handling. When the map mode is
disabled and the map mode is in twips, then in general it's possible to
send mouse coordinates in twips. The scrollbar is usually in pixels, so
add extra code to still make this possible.

(cherry picked from commit d7acb44b148893fe0cc48a54c3eb73406c251668)
