* Switch to using Canon sensor type instead of camera models.
There are a ton of camera models that reuse the same sensor
so it's just confusing and forever incomplete to try and cover
all models.
* Delete all redundant Canon camera models..
* Leave only the Canon camera models that are special, that is
have non regular sensor sizes.
* Fix a few errors in some Canon models.
* Capitalize a few unrelated sensor presets for consistency.
* Added presets for GoPro and iPhone.
Their distortion models and shutter isn't really supported ATM
but tracker is robust enough to give reasonable tracking and
solving results.
Presets are from Daniel Salazar and Sebastian Koenig, thanks!
Differential Revision: https://developer.blender.org/D264
- 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
