Rename $regex_rule variable to $image_urls_regex to make it more clear what it is matching.
Update regular expression pattern to produce a match if density descriptors are used (e.g. /wp-content/uploads/example.jpg 1x, /wp-content/uploads/example@2x.jpg 2x). The change made was w to [wx].
Update Cache_Enabler_Disk::_convert_webp() to start the conversion as soon as one image is found instead of counting them.
Fix Cache_Enabler_Disk::_image_path() to return correct image path if installation is in a subdirectory. This issue was introduced in version 1.4.8 when allowing images in any directory to be replaced instead of images only in the uploads directory (PR #116). Previously the subdirectory name was being duplicated (from the ABSPATH and the received $image_url). The leading slash in the $image_url_path variable will always be trimmed in case a relative URL is provided without a leading slash. The first directory is then taken as the potential installation directory (e.g. wordpress/). If the first directory is in the ABSPATH it is removed from the ABSPATH (e.g. /path/to/public/wordpress/ would become /path/to/public/). The $image_path is then created by concatenating the potentially updated ABSPATH and $image_url_path (e.g. /path/to/public/wordpress/wp-content/uploads/example.jpg).
