[Xastir] Possible maps bug

Hi Robert,
There is a limit to the size of the returned OSM static map of 2Kx2K.
That OSM map typically must be larger than the window because OSM maps
are Mercator projections and Xastir is not. As a result, the present
OSM implementation limits the requested map size and then tries to
align it with the display. So not filling the window is expected,
alignment errors are unexpected and probably a bug.

I am presently working on new code that will use OSM tiles. That code
not be impacted by the 2Kx2K limit, but it is still a
work-in-progress. Working with tiles will also require me to revisit
the alignment calculations.

Until I get the tiles working, the work-around will have to be- use a
smaller window. Sorry about that.

...jerry

I have a large monitor (2048x1152) and when I maximize the window, the maps only fill about 1/3 of the window, and are off-position from the stations. This seems to be dependent on the width of the window - smaller than about 1420px wide, it switches from buggy to fine. Neither the height nor zoom appears to matter.
