[Eclipse Skin] Vault: Icon Highlight Example

[Eclipse]

While the vault's item highlighting indeed barely visible in Eclipse UI, it exists (on your attached sample, the first slot's 1 pixel bottom line is slightly brighter, still undetectable).
The graphic is the same used in the Social listings (those thin separators), for example.
If I brighten or thicken it for the sake of the vault, it will affect other highlights in the UI, so I do not intend to change at this point.
