/* CalendarItemTextStyles.css
 *
 * To show event/task status and priority with CSS text styling,
 * save this CSS in your profile [1] chrome directory,
 * and import this CSS in your userChrome.css [2].
 * 
 * For Sunbird, the userChrome.css path may be something like the following
 *  w2k: %APPDATA%\Mozilla\Sunbird\Profiles\NNNNN.default\chrome\userChrome.css
 *  gnu/linux: ~/.mozilla/sunbird/NNNNNN.default/chrome/userChrome.css
 *
 * 1. Save this file in your profile as chrome/CalendarItemTextStyles.css
 * 2. Add the following to profile file chrome/userChrome.css (create if none):
 *   @import url("CalendarItemTextStyles.css");
 *
 * Tested on Sunbird 0.9.
 *
 * Known issues: 
 * - Privacy
 *   - privacy attributes are not yet added to events, so it is
 *     impossible to style private events based on CSS alone.
 * - Status
 *   - In DayView and WeekView, <xul:description> does not implement
 *     CSS text-decorations: underline, line-through.
 *     - Instead of underline, this version uses a workaround using
 *       border-bottom, but the bottom may be far from the text.
 *     - Instead of line-through, cancelled/completed items are faded.
 *       Completed items have solid line; cancelled items have broken line.
 *   - There is no css text-decoration for dashed underline.
 *     Instead, dashed underline is simulated with border-bottom
 *     with border-style: dashed.
 *   - In the event list and task list, <xul:tree> does not implement
 *     CSS opacity.  Instead of opacity, GrayText color is used.
