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.
