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.
