The _dither part used to be for i586, but there is also a plain C
variant in there now. The x86_dither is recommened for any
i386-compatible CPU. It activates assembly optimizations for i586, MMX,
SSE etc. at runtime. All i386-based decoders are merged in there ---
except i486, which is indeed a special beast.

... yeah, I'll have to investigate that. Though, the i486 decoder has
mostly historical value ... or just vor bragging rights to get fast
decoding on a vintage i486 CPU.


Alrighty then,

Thomas
