Image filter: fixed image_filter rotate inheritance. Configurations like location /i/ { image_filter resize 200 200; image_filter rotate 180; location /i/foo/ { image_filter resize 200 200; } } resulted in rotation incorrectly applied in the location /i/foo, without any way to clear it. Fix is to handle conf->angle/conf->acv consistently with other filter variables and do not try to inherit them if there are transformations defined for current location.
