When detecting a panorama in 59 rows of 11 images per row, APG find/apply a rectilinear projection!!! To change projection into cylinder projection takes ages in my PC. mmh, I should probably wait for this one : http://www.gla.ac.uk/news/headline_183814_en.html
Anyway, This would be nice if APG could apply right projection from first shot. This will save recalculation time.
