Bone selection overlay is only available in pose mode. and when active overrules the selection buffer. This is currently `tricked` by switching the draw engines, but this is an exception. Not sure how to solve this in a better way. After this is solved we can look at how to localize the dim effect to only the objects connected to the active armatures. Currently it dims the whole screen (including background). @campbellbarton I added you as reviewer as it you have done a lot in the DRW_draw_select_loop Reviewers: campbellbarton, fclem Reviewed By: fclem Subscribers: campbellbarton Tags: #bf_blender_2.8, #code_quest Maniphest Tasks: T54983 Differential Revision: https://developer.blender.org/D3241
