Can we have the option to have the custom sleep screen images not fiddled with before display? Either by allowing xth images or by performing dumb posterization (indexing color to [0, ~85, ~170, 255] then mapping those to the 2-bit screen values?

I had performed the indexing and dithering myself in photoshop but as of now that is a waste of time since crosspoint is doing it's own thing after that. The suggested change would end up allowing the user to determine how the image will be displayed if they choose to preprocess it.

The normalization performed now performs very poorly for images with non-uniform pixel distribution.
