2013-05-25	use math functions rather then macros for bicubic interpolation.	Campbell Barton

2013-03-28	Fix #34782: Video Editor - Substract after transform fails	Sergey Sharybin
	Couple of precision issues here: - Interpolation was rounding trunkcating colors, and because of some precision issues value 254.999 became 254 leading to troubles later. Now color interpolaiton will do rounding to nearest int. - Subtract was setting channels to something negative which confused color management (especially negative alpha), Now subtract effect will clamp channels to 0 from bottom and also do some tricks to prevent small alpha which could also confuse color management.
2012-11-17	Fix #33210: Diffuse Pass in scale node leads to problems	Sergey Sharybin
	Was own mistake in render layers interpolation changes.
2012-11-11	Code de-duplication in imageprocess.c -- made it use interpolation functions ↵	Sergey Sharybin
	from blenlib
2012-11-10	Solved issue with distorted compositor results in some cases	Sergey Sharybin
	Originally issue was discovered when using stabilization and movie distortion nodes, but in fact issue was caused by render layer node always doing nearest interpolation. Now made it so this node will respect sampler passed to it's executePixel function and do an interpolation. Added two new functions to do bilinear/bicubic interpolation in float buffer with variable number of components per element, so it could interpolate 1, 3 and 4 component vectors. This functions currently mostly duplicates the same functions from imageprocess.c and it should actually be de-duplicated. Think it's ok to leave a bit of time with such duplication, since functions should be generalized one more time to support byte buffers, which could backfire on readability. Also removed mark as complex from stabilization node, which isn't needed sine int fact this node is not complex.
