Why is it called "pixelPerDegree" in ImageryInfo? Apparently, the value
is in pixels per unit in projected space ("pixelPerEastNorth").
There is an interesting bug in ImageryLayer.getPPD(), line 86: It
returns Main.getProjection().getDefaultZoomInPPD() when mapframe is
null. However the "Projection-PPD" is not the same, as the
"Imagery-PPD", in fact they are inverse to each other. (Or
NavigatableComponent line 99 is wrong, I haven't investigated the full
history if this...)
I suggest to rename all this, so it makes more sense.
