WowAce

What steps will reproduce the problem?
1. Default settings
2. Targeting an object
3. Looking at the unit frame for target, and then comparing to the player unit frame.

What is the expected output? What do you see instead?
There should be a border of 1 black pixel on the left edge of the target unit frame, like the player frame's border, but instead the border is 2 pixels.

What version of the product are you using?
The latest version for patch 3.2

Do you have an error log of what happened?
I don't believe there is an error log as this is something that is always there.

Please provide any additional information below.
I have uploaded a picture comparing the two frames, showing the difference between the two borders of the target frame, and player frame.
