// Class : PaletteGroup
// Description : This is the highest level of grouping for
// TextureImages. Textures are assigned to one or
// several PaletteGroups based on the information in the
// .txa file; each PaletteGroup is conceptually a
// collection of textures that are to be moved around
// (into texture memory, downloaded, etc.) in one big
// chunk. It is the set of all textures that may be
// displayed together at any given time.
