* bink: make IDCT take 32-bit inputKostya Shishkov2011-07-271-0/+119
Since IDCT transforming 32-bit input to 8-bit output is unusual and unpractical for most codecs, move Bink IDCT into separate context. Get rid of an additional permutation table while at it since SIMD support for Bink IDCT is unlikely to be implemented in foreseeable future. Quantisation tables also have to change type to signed for proper dequantisation of DCT coefficients. Signed-off-by: Mans Rullgard <mans@mansr.com>
