avcodec/hqx : Don't zero in small chunks, don't zero twice
13 mars, par Andreas Rheinhardtavcodec/hqx: Don't zero in small chunks, don't zero twice Up until now, decode_block() zeroed every block (of 128 bytes) before decoding a block; yet this is suboptimal for all modes, because all modes need to reset all the blocks they use anyway and so it should be done in one go for all blocks. For the alpha modes (where blocks need not be coded) all blocks are zeroed initially anyway, because decode_block() might not be doing it, so zeroing there again for the coded blocks is a waste.
