RGBLUT is in the older 1.5 Masktools.dll

Mmmm... how do I change the luma with RGBLUT? I have to do weighted R, G, B adjustment for that, or is there more simple way?
Perhaps it'd better stay in the YV12 colorspace all the way. Is there a command to easily adjust the Y, U, V channels? A YUVAdjust() would be the best instead of RGBAdjust()
