avformat/mov: rewrite aspect from matrix code
The original code was intended purely for rotation == 0 In cf70ba37ba74089a18295b29e77dead0a3222c9e the condition was changed to use it only for rotation != 0 which broke the cases for which it was intended to be used as well as breaking cases for which it was not intended to be used. This changes the code so it could work for the more general case and fixes the regressions If you have sample files that are not handled correctly please open tickets or mail me!
