This patchset improves especially support for SMUSHv1 (Rebel Assault 1), adds missing codecs and functions and improves reliability of SMUSHv1/v2.
#1 improves frame size detection. #3 changes the left/top values to signed, as RA1 makes heavy use of negative offsets. #4 adds workarounds for RA1 oddities. #5-10 add missing codecs and fix existing ones. #11-12 implement the store/fetch feature for RA1 codecs: the RA1 engine stores the raw frame object data in an aux buffer and replays that when necessary. Is required for codecs1-34 since they only work on parts of the buffer, and the existing scheme breaks the visuals here. This patchset makes almost all RA1 videos now playable with generally correct content, although some hiccups remain.
