Align: put image in event box
	print coordinates of mouse clicks
trying to make marker search adjustable from within DAQ
put marker filter and center of mass calculation in DAQ
* need to rework correlation of optical marks to SEM marks
* need to audit pixel calculation
refactored marker search:
* extract align_init
* extract align_xform
* fixed indexing of files: SEM image numbering is replaced by OPT image numbering,
  but the numbering is saved for later (e.g. for reading the original marker search box)
align:
* put errors for markers in field next to marker
* progress bar during filtering
align: auto recalculate xform when marker checkbox is changed
align: audited marker search. I believe the coordinates we get now from
adjusting filter settings in DAQ are actually correct.
align: fix order when loading SEM images on first load, they were going to the wrong SEM slots
