-// -- Additional colors --
-//
-// Colors are resolved using ColorIndex().
-// It resolves the colorTable entry using the ASCII value.
-// If we want to add colors, we have to use correct ASCII chars.
-// As the last value is 0x39 (9), we have to go on with 0x3A (:)
-// So the next chars would be:
-// 0x3A (:), 0x3B (;), 0x3C (<), 0x3D (=), ...
-//
-// The problem though is that I_CleanString doesn't know we added colors, so we have to adapt that as well!
