Merge of r4979, r4982: image filter configuration inheritance. *) Image filter: configuration inheritance fixes. The image_filter_jpeg_quality, image_filter_sharpen and "image_filter rotate" were inherited incorrectly if a directive with variables was defined, and then redefined to a literal value, i.e. in configurations like image_filter_jpeg_quality $arg_q; location / { image_filter_jpeg_quality 50; } Patch by Ian Babrou, with minor changes. *) 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.
