Dan Brown 31f1dca8a8 Added detection and thumbnail bypass for apng images ... Adds apng sniffing when generating thumbnails with retained ratios to serve the original image files, as we do for GIF images, to prevent the image being resized to a static version. Is more tricky than GIF since apng file mimes and extensions are the same as png, we have to detect part of the file header to sniff the type. Means we have to sniff at a later stage than GIF since we have to load the image file data. Made some changes to the image thubmnail caching while doing this work to fit in with this handling. Added test to cover. For #3136.		2022-01-04 13:10:35 +00:00
