Microsoft WorldWide Telescope 6.1.1.0

What's new in this version:

Code changes:
- Tweaks to how tour files are created to ensure interoperability with the web client when including progressive HiPS catalog data sets
- Fix mirror-imaging of .OBJ 3D model files

Date updates:
- Add six new Mercury planetary maps
- Mercury MESSENGER MDIS Global Basemap BDR 166m
- Mercury MESSENGER MDIS Global Basemap LOI 166m
- Mercury MESSENGER MDIS Basemap MD3 Color Global Mosaic 665m
- Mercury MESSENGER MDIS Global Color Mosaic 665m v3
- Mercury MESSENGER MDIS Basemap Enhanced Color Global Mosaic 665m
- Mercury MESSENGER MDIS DEM Global Color Shaded Relief 2km v1
- Add “constellation” information to all of the core catalog records. This is mostly a matter of tidyness but should be helpful for updating the search indices used by the web client.
- Remove a smattering of images with bad astrometry with no clear path to recovering the correct coordinates. Fix up negative zoom levels for some other images
