    Refactored idct routines and headers · 3a8c43a4
    Peter de Rivaz authored
    This change is made in preparation for a
    subsequent patch which adds acceleration
    for the highbitdepth transform functions.
    The highbitdepth transform functions attempt
    to use 16/32bit sse instructions where possible,
    but fallback to using the C implementations if
    potential overflow is detected.  For this reason
    the dct routines are made global so they can be
    called from the acceleration functions in the
    subsequent patch.
