// MultiDecomp
// ver. 0.5
// Decomposes an image into as many layer slices as the user would like, based on the techniques in the 'HighPass Sucks' thread.
// by *THAT* HP Guy.
// *** USE AT YOUR OWN RISK ***
// Version Changes:
// 0.2 --
// Introduced sanity checks
// Check bit depth and use modes as appropriate
// Verify # of layers at outset and copy / copy merged as appropriate
// 0.3 --
// Improved layout
// 0.4 --
// Included Clipped Curves adjustment layers option
// 0.5 --
// Fixed Curves bug
// Round display values for layer names
// To Do:
// 1.0 --
// Improve accuracy / investigate multilayer recomposition from source in 8bit
// Ideas?
