* TODO:
- * - handle dragging slider better
- * - increase with of the paging area
+ * - implement autorepeat for paging
* - possition buddy controls
- * - better tic handling.
- * - more notifications.
- * - TBM_SETRANGEMAX & TBM_SETRANGEMIN should only change the view of the
- * trackbar, not the actual amount of tics in the list.
- * - TBM_GETTIC & TBM_GETTICPOS shouldn't rely on infoPtr->tics being sorted.
+ * - custom draw notifications
+ * - implement TBS_DOWNISLEFT
+ * - fix tics drawing for TBS_BOTH
+ * - use fLocation (TBTS_{TOP,LEFT,BUTTOM,RIGHT})
