Larvae from FIMTrack files cannot be dragged and dropped
Steps to reproduce: Load file embl_sample_table.csv from artefact fimtrack_sample_tables.tgz.
EDIT: Active areas for larvae are sized assuming mm as space unit, while FIMTrack data are expressed in pixels. A quick estimate of the median larval body length would help in adjusting active areas. Meanwhile, being accurate enough to pick the middle point of the larva, larvae can still be dragged and dropped. The issue with space units also affect the active area around a track; the body may not be included within such an active area.
