Subject: fixed the decoder when using 8x8 transform
X-Git-Tag: v1.3.0~1217^2~380^2~160^2
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=7189198d53123273fe89f20e35ee11ae45ee8fcd;p=libvpx

fixed the decoder when using 8x8 transform

updated the decode_macroblock logic to reflect that 8x8 transform is
not used for "SPLITMV". Also fixed an issue where 2nd order haar block
has wrong dequant/idct process.
