i hadn't added it but could easily prioritise it. Cesar will love that :)

this is the general strategic idea, with the effect being to reduce
the offset allowed is between 0 and 63. zdimsz ydimsz and xdimsz may be
between 1 and 64. do you need beyond that?
if so, i just noticed that applydim *might* be redundant (set the dimension
to 1 and it's the same effect).
/mp3_0_apply_window_float.s is very unclear (arbitrary non-sequential
could you outline in pseudo-assembler what you need?
