Options for MySprite constructor

The required data string in the MySprite constructor doesn't match up exactly with the .dds filenames. Is there a list of the allowed strings? So far I've found

• SquareSimple
• SquareHollow
• Circle
• CircleHollow
• Arrow
• Cross
• Triangle
• RightTriangle
  
• Grid
• Construction
• Danger

But I can't find the string for "default_offline.dds", "default_online.dds", "NoEntry.dds", the brackets, and "Semi_Circle.dds". Are there more, including hidden ones like...
