4b75be801e initial version of Lab2RGB_f tetrahedral interpolation written
RGB2Lab_f added, bugs fixed, moved to float

several bugs fixed

LUT fixed, no switch in tetraInterpolate()

temporary code; to be removed and rewritten

before refactoring

extra interpolations removed, some things to do left

added Lab2RGB_b +XYZ version, etc.

basic version is done, to be sped up

tetra refactored

interpolations: LUT for weights, refactor., etc.

address arithm optimized

initial version of vectorized code added (not compiling now)

compilation fixed, now segfaults

a lot of fixes, vectorization temp. disabled

fixed trilinear shift size, max error dropped from 19 to 10

fixed several bugs (255 vs 256, signed vs unsigned, bIdx)

minor changes

packed: address arithmetics fixed

shorter code

experiments with pure integer calculations

Lab2RGB max error decreased to 2; need to clean the code

ready for vectorization; need cleaning

vectorized, to be debugged

precision fixed, max error is 2

Lab->XYZ shortened

minor fixes

Lab2RGB_f version fixed, to be completely rewritten using _b code

minors

moved to separate file

refactored Lab2RGB to float and int versions

minor fix

Lab2RGB_f vectorized

minor refactoring

Lab2RGBint refactored: process methods, vectorize by 4 pix

cleanup extra code

code copied to color.cpp

fixed blue idx bug

optimizations enabled when testing; mulFracConst introduced

divConst -> mulFracConst

calc min time in perf instead of avg

some warnings fixed

changes transferred to color.cpp

whitespace

shift negative fixed

more warnings fixed

"constant condition" warnings fixed, little speed up

minor changes

unfinished work

it works, need to fix TODOs

constants made bit exact; minors

changes moved to color.cpp

fixed 1 bug and 4 warnings
