...when a color profile is active This commit doesn't fix anything, but it prepares the code to do the right thing: It passes the actual raw image pixels through the entire color picking mechanism to the widgets which display colors, particularly GimpColorFrame. This is needed for GimpColorFrame's "Pixel" mode (as opposed to its RGB, HSV etc. modes) which is supposed to show the raw pixel values from the image. Before this commit, it was recreating the raw pixel values from the GimpRGB value it knows, which will become impossible when we correctly pick color managed GimpRGB values soon.
