-update_imadoc: copy the timing information of the movie file avi in the new xml file when a geometry_calibration is performed
-set_grid: modified to produce grids in px coordiantes and to display the produced grid
-geometry_calib: display the point with max error
-civ: bug corrected for copying avi movies to png files
-uvmat: small bug fixes
-px_XYZ: introduce default values for Calib parameters
