[Freeciv-Dev] Re: (PR#4543) scaling overview map

["rwetmore@xxxxxxxxxxxx" <rwetmore@xxxxxxxxxxxx>]

The overview map is a special case where scaling *must* preserve
relationships because of the fine granularity. This means you need
all tiles to have identical "n x m" sizes and the scaling is jerky
and pretty much two dimensional.

In general this is set not for the overview map aspect, but for the
placement of the other widgets about it so the info boxes have a
consistent size and character length.

Probably not a good thing until screen resolutions become such that
the overview tile size is 8 x 8 instead of 2 x 2, i.e. video screen
size is 4096 x 3072 vs 1024 x 768.

I could live with an overview map that "floated" in a black window
of appropriate size and scaled *if* it got to be less than halfsize
in both directions, but not continuous scaling.

Cheers,
