[Freeciv-Dev] Re: Native Coordinates [Was:[PATCH] Map cleanups (PR#1208)

["Ross W. Wetmore" <rwetmore@xxxxxxxxxxxx>]

Scrollbars are connected more closely to the overview map (the little 
one to the side) rather than the actual large scale map in the current 
code. They set the origin point on the overview from which the bounds
of the canvas spread out in appropriate standard or isometric directions.

Or to put it differently, they and the overview are using standard 
coordinates, while the canvas is using isometric, hence the disconnect
in this case.

In the corecleanups, the overview is handled in native coordinates, so
a true isometric map will scroll normally, but a trident view will be
the one to drive you nuts :-).

This clearly is one of the things to improve on, either attach them to
the right window, or change their coordinates to reflect the view they
are attached to. It is coming ...
