Fix delay application in synchroniser
Description
Apply delay on the matrix or the frame depending on the delay sign
Update the slot to allow settings delay different for each timeline.
- The key needs to be either frameDelay_i or matrixDelay_i where i is the index of the timeline in the input vector
- The value should be a positive value.
- The delay will be applied to the corresponding timeline. Once synchronized, the effective frame/matrix
- picked by the algorithm will be in the past with a temporal offset of delay.
Closes #936 (closed)
How to test it?
Run an application with a frame/matrix synchroniser.
Add a massive (2000) timeshift in one of the tl, and verify that it unsynchs the elements which are synch normaly.
