[*] Rename files of: - Calib3d.pas in calib3d_s.pas - Tracking.pas in tracking_s.pas To ensure conformity with the file names OpenCV library [!] Modules used in the project without the inclusion of relative paths. Added instructions on how to add the module search path (see readme_en.txt) [+] Added an example Posit (cvReleasePOSITObject, cvPOSIT and others) (thanks to Frans van Daalen (CLubfitter73)) Signed-off-by: Laex <laex@bk.ru>
