This is a Derma version of the manually drawn Default Player Class HUD Element which is now gone. It integrates with the UIManager and FontManager and scales with the ScreenSize instead of being a fixed small size.
Even though git internally knows the difference between upper and lower case, all of it's commands rely on the file system to do so as well. This results in incorrect behavior when renaming A to a for example, as the source and destination is identical on the file system according to git. Windows does support such renames, but git seems to shit itself.
