+/**
+ * GOTCHA #1: When sending the headers for caching, we must send Expires,
+ * Last-Modified, Pragma, and Cache-Control headers. If we don't PHP
+ * will makeup values that will break the cacheing.
+ *
+ * GOTCHA #2: If the current template does not contain a template named
+ * stylesheet.tpl, this cacheing will break because filemtime() won't
+ * work. This is a problem e.g. with the default_advanced template
+ * that inherits CSS properties from the default template but
+ * doesn't contain stylesheet.tpl itself.
+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!)
+ * Possibly naive suggestion - template can define its own default
+ * template name
+ *
+ * GOTCHA #3: If the user changes user prefs for things like font size then
+ * the mtime should be updated to the time of that change, and not
+ * that of the stylesheet.tpl file. IDEA: can this be a value kept
+ * in user prefs (always compare to actual file mtime before sending
+ * to the browser)
+ *
+ * Comment re gotcha #3: If we only define basic font prefs here, we really
+ * only need to refresh the cache if one of the font prefs changes.
+ * Possibly some type of "force nocache flag could be set if a font pref is
+ * changed?
+ *
+ * TODO: Fix this. :)
