[Xastir] Possible maps bug

[Jerry Dunmire]

Hi Robert,
Thanks for the update. I am really happy to hear that the alignment
correct (I did try to get that right) and that your home is once again
where it belongs!

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.
