This implements a new overlay that blends the bakground color over the objects that are not in the same mode as the active object, making them fade with the background. This is especially needed for sculpt mode as there is no other overlay or indication in the viewport to display which object is active. This is intended to be used with D7510 in order to have a faster workflow when sculpting models with multiple objects. Reviewed By: fclem Differential Revision: https://developer.blender.org/D8679
