Outlined Shownames Don't Center Properly

[Samevi]

When a showname is outlined, it fails to center properly - eg. while long names like Ryunosuke are centered properly, shorter names get shoved to the right. See images.

To reproduce
Steps to reproduce the behavior:

1. Use a theme with outlined shownames set to center alignment.
2. Witness as the alignment goes kaput depending on the length of the names.

Expected behavior
center showname pl0x
