/**
 * TTheme class
 *
 * TTheme represents a particular theme. It is merely a collection of skins
 * that are applicable to the corresponding controls.
 *
 * Each theme is stored as a directory and files under that directory.
 * The theme name is the directory name. When TTheme is created, the files
 * whose name has the extension ".skin" are parsed and saved as controls skins.
 *
 * A skin is essentially a list of initial property values that are to be applied
 * to a control when the skin is applied.
 * Each type of control can have multiple skins identified by the SkinID.
 * If a skin does not have SkinID, it is the default skin that will be applied
 * to controls that do not specify particular SkinID.
 *
 * For globalization, Themes remove all css files that end in ".*rtl.css" or
 * ".*rtl.(media).css".  Then if there is Application Globalization, and
 * globalization current culture is Right-to-left then the rtl css files are
 * re-added at the end of the css files so rtl css has priority.
 *
 * Whenever possible, TTheme will try to make use of available cache to save
 * the parsing time.
 *
 * To apply a theme to a particular control, call {@link applySkin}.
