9 * TODO:
10 * - Imagelist support (partially).
11 * - Callback items (under construction).
12 * - Order list support.
13 * - Control specific cursors (over dividers).
14 * - Hottrack support (partially).
15 * - Custom draw support (including Notifications).
16 * - Drag and Drop support (including Notifications).
17 * - Unicode support.
18 *
19 * FIXME:
20 * - Replace DrawText32A by DrawTextEx32A(...|DT_ENDELLIPSIS) in
21 * HEADER_DrawItem.
22 * - Little flaw when drawing a bitmap on the right side of the text.
