Anton Khirnov	fe80fa53bc	4xm: replace forcing EMU_EDGE by a copy The decoder currently sets CODEC_FLAG_EMU_EDGE and relies on get_buffer2() to always provide buffers with linesize == 2 * width. This is wrong, since we place no such restriction on get_buffer2() implementations. Fix this by decoding into internal buffers and copying them to output frames. Since this is a very obscure decoder, the performance hit should not be an issue.	11 years ago
