File browser thumbnails for raw images start with a minimally-processed images. These images are cached and image adjustments are applied on top. The black level is "baked-into" the cached image. Therefore, to reflect the black level adjustments in the thumbnail, one of two options are required: 1. Cache an image before the black level is applied and process the black level on top of this image. 2. Recreate the base image with the new black level and cache it. The first option yields better performance when the user changes the black level. However, it requires other base adjustments to be applied every time, such as the camera multipliers. The second option requires the base image to be recreated every time the black level is changed. This commit implements the second option. It minimizes code changes, and therefore possible bugs. It does add a performance penalty when the black level changes, but the black level adjustment is rarely used.
