the class CSSCompressor method getRewrittenCSS.

/**
 * Get the rewritten version of the passed CSS code. This is done by
 * interpreting the CSS and than writing it again with the passed settings.
 * This can e.g. be used to create a compressed version of a CSS.
 *
 * @param sOriginalCSS
 *        The original CSS code to be compressed.
 * @param aSettings
 *        The CSS writer settings to use. The version is used to read the
 *        original CSS.
 * @return If compression failed because the CSS is invalid or whatsoever, the
 *         original CSS is returned, else the rewritten version is returned.
