working transparency support for gl646 based scanners
- add move to transparency adapter function to command set - no warmup when using transparency adapter - increase maximum warmup time to match HP3670 requirements - tune HP3670's transparency adapter geometry - handle calibration area geometry in gain calibration - add simple move head function for gl646 based scannersmerge-requests/1/head
