151 * GOTCHA #1: When sending the headers for caching, we must send Expires,

153 * will makeup values that will break the cacheing.
154 *
155 * GOTCHA #2: If the current template does not contain a template named
156 * stylesheet.tpl, this cacheing will break because filemtime() won't
157 * work. This is a problem e.g. with the default_advanced template
158 * that inherits CSS properties from the default template but
159 * doesn't contain stylesheet.tpl itself.
160 IDEA: So ask the Template class object to return the mtime or better yet, the full file path (at least from SM_PATH) by using $oTemplate->get_template_file_path(stylesheet.tpl) but this is still a problem if the default template also does not have such a file (in which case, we fall back to SM's css/deafult css file (so in that case, go get that file's mtime!)
161 * Possibly naive suggestion - template can define its own default
162 * template name
163 *
164 * GOTCHA #3: If the user changes user prefs for things like font size then
165 * the mtime should be updated to the time of that change, and not
166 * that of the stylesheet.tpl file. IDEA: can this be a value kept
167 * in user prefs (always compare to actual file mtime before sending
168 * to the browser)
169 *
170 * Comment re gotcha #3: If we only define basic font prefs here, we really
171 * only need to refresh the cache if one of the font prefs changes.
172 * Possibly some type of "force nocache flag could be set if a font pref is
173 * changed?
174 *
175 * TODO: Fix this. :)
