System Information
Windows 7 x64. GTX580

Blender Version
Broken: 2.69.0 Official (r60995) & 2.70RC1 (Hash: 19f7f9a)

Short description of error
When assigning 2D objects with faces (not wire objects) such as a plane to be a custom bone shape, it only is visible (in viewport) from one side. Even if "Double Sided Normals" is selected.

Exact steps for others to reproduce the error

Start Blender with default scene.
Add armature --> Single Bone
Add Mesh --> Plane
Go to the bone properties, and assign the plane as a custom shape.
The plane itself (as an object) displays double sided but the plane representing the bone appears only one sided.
Turning on "Double Sided" under mesh Normals doesn't help.

Also tested it with other objects like a hemisphere (UV sphere with half its vertices removed)

Developer note:
This is a side effect of optimization which does backface culling for armatures. The idea here would be to:

Always do backface culling if there's no custom shape
If there's custom shape do backface culling if it's enabled in view3d settings.

@brecht, does it sound good for you?
