Ganesh Ajjanagadde	9ee1feaa7c	avfilter/af_afade: improve accuracy and speed of gain computation Gain computation for various curves was being done in a needlessly inaccurate fashion. Of course these are all subjective curves, but when a curve is advertised to the user, it should be matched as closely as possible within the limitations of libm. In particular, the constants kept here were pretty inaccurate for double precision. Speed improvements are mainly due to the avoidance of pow, the most notorious of the libm functions in terms of performance. To be fair, it is the GNU libm that is among the worst, but it is not really GNU libm's fault since others simply yield a higher error as measured in ULP. "Magic" constants are also accordingly documented, since they take at least a minute of thought for a casual reader.
