- Changed some names so now people who aren't really familiar with
motion tracking can understand what they exactly means
- Also cleaned up and rephraded some descriptions
- Changed behavior of operator which creates empty for 2d tracks:
now it operates on all selected tracks rather than active track only
- Added checkbox to enable/disable rotation stabilization
- Added support of variable size sensor width and height.
- Added presets for most common cameras, also new presets can be defined by user.
- Added option to control which dimension (vertical or horizontal) of sensor
size defines FOV. Old behavior of automatic FOV calculation is also kept.
- Renderer, viewport, game engine and collada importer/exporter should
deal fine with this changes. Other exporters would be updated soon.
