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