-0.01: New App!
-0.02: Fix marker position, color, and map scaling
-0.03: Show widgets (mainly so we can use the GPS recorder widget)
-0.04: Move map rendering to a module (fix #396)
-0.05: Show currently active gpsrec GPS trace (fix #395)
-0.06: Add support for scrolling, option for 3 bit maps
-0.07: Move to 96px tiles - less files (64 -> 25) and speed up rendering
-0.08: Update for drag event refactor
-0.09: Use current theme cols when drawing GPS info
-0.10: Improve scale factor calculation to fix scaling issues (#984)
-0.11: Add slight offset to OSM data to align it properly (fix #984)
-      Fix alignment of satellite info text

-* Could maybe use palettised output?
-* Could potentially use a custom 16 color palette?
-* Allow user to choose size of map area to be uploaded (small/med/large)
-* What is faster? Storing as a compressed image and decompressing, or storing decompressed?
