Curve points of tracks curves now can be selected for X and Y channels
separately and can be moved along Y axis of curve viewer, points currently
can't change frame they belong to. This allows to smooth spikes caused by
unwanted marker jump.
Also fixed some mistakes in cancel transform in cases when locked tracks
were being trying to be moved; fixed incorrect calculation of marker speed
for curve drawing.
This commit implements basis stuff needed for object tracking,
use case isn't perfect now, interface also should be cleaned a bit.
- Added list of objects to be tracked. Default there's only one object called
"Camera" which is used for solving camera motion. Other objects can be added
and each of them will have it;s own list of tracks. Only one object can be used
for camera solving at this moment.
- Added new constraint called "Object Tracking" which makes oriented object be
moving in the save way as solved object motion.
- Scene orientation tools can be used for orienting object to bundles.
- All tools which works with list of tracks or reconstruction data now
gets that lists from active editing object.
- All objects and their tracking data are available via python api.
===========================
DeBalie commit (main changes only):
- Code cleanup
- Selectable tracking graph curves and curve knots
- Graph curve and curve knots can be deleted now
- Fixed wrong write when linking libraries
(error is caused by hardcoded cound of linkable ID blocks)
- Fixed for KLT tracker when using keyframe adjustment
