GMapPlot Coordinate Axes #2940
Description
GmapPlot no longer displays lat/lon coordinates in useful formats. It's hard to quantify this due to issue #2939, but it also appears that points are appearing ~20 pixels to the left of where they ought to be projected on a map. The code below is the exact same as from issue #2822.
