Summary [GTK] Animations not played properly when using synchronous decoding

For PNG and GIF images, async decoding is used if the file size is bigger than a threshold, otherwise sync decoding is used. Bug 170333, which happens because async decoding stopped being used, revealed that sync decoding is not working properly.

There seems to be an error in ImageFrameCache::destroyDecodedData(). Theoretically this should destroy all the decoded frames except one we want to keep, but what it's actually doing is destroying all the odd ones (including the one we want to keep if it's odd).
