JIC PicViewer (WIP)

[rmackay9]

This WIP PR adds a new offline picture viewer to MAVProxy for use in the Japan Innovation Challenge.

The design (and some code) borrows heavily from the Canberra UAV team's CUAV tool

How-to-use:

• MAVPicViewer application is installed along with MAVProxy (much like MAVExplorer)
• Use the MAVPicViewer icon to start the application (if visible) or start the mavpicviewer.py script. Once started 3 windows should appear:
  • Image Viewer shows the current image and allows users to set a single POI per image
  • SlipMap shows a map of the area with the current image's area highlighted in green. This improves the reviewers situational awareness
  • Mosaic shows thumbnails of all images

Enhancements planned:

• allow users to click on the map and have the Image and Mosaic views jump to the closest image
• support saving the current image including POI to a new image
• improve visibility of the POI's lat,lon (and also the cursor's lat,lon)
• reduce the Mosaic so that it only shows images with POI defined (?)
• combine into a single window?
