The problem is the county names still lie under the labels of the stations.
Aren't the station labels _always_ on top? I don' think you can raise
the map above the station.
Correct. We do this:
1) draw maps->pixmap1
2) copy pixmap1 -> pixmap2
draw weather alerts onto pixmap2
3) copy pixmap2 -> pixmap3
draw stations & tracks onto pixmap3
4) copy pixmap3 -> display
There are valid reasons for doing it this way, mostly for
speedups/efficiencies, as most of the time we just have to do #3 and
#4, and only when new weather alerts come in do we start at #2. We
very seldom start processing at #1 except for perhaps mobile Xastir.
