Improve brightness scaling for images #2

When input images for the WLED frame have dark backgrounds, the remaining elements are very bright, and vice versa.

Basically, we have to account for uneven brightness in the original image and preserve that as much as possible.

Also: dark colored backgrounds have brightness scaled up making them a completely different color..
