By default select wasn't picking the nearest object, this could have been fixed by not clearing the depth buffer, but calling GPU_select_(begin/end) without the binded frame-buffer caused issues for depth-picking. So move GPU_select begin/end to a callback. This also has the advantage that only needs to populate the engines once to draw two passes. Note that cycling through objects fails with occlusion queries still, will fix shortly.
