[FFmpeg-devel] [PATCH 1/2] lavu/tx: rewrite internal code as a tree-based codelet constructor

[Lynne]

This commit rewrites the internal transform code into a constructor
that stitches transforms (codelets).
This allows for transforms to reuse arbitrary parts of other
transforms, and allows transforms to be stacked onto one
another (such as a full iMDCT using a half-iMDCT which in turn
uses an FFT). It also permits for each step to be individually
replaced by assembly or a custom implementation (such as an ASIC).

Patch attached.
