* - All notifications.
* Changes Guy Albertelli <galberte@neo.lrun.com>
* 1. Correct use of fStyle for fMask
* 2. Rewrite to support putting bands in rows, also supports GETROWCOUNT
* and GETROWHEIGHT.
* 3. Make fMask in internal band info indicate what is valid rather than -1.
* 4. Correct output of GETBANDINFO to match MS for iImage, lpText
* 5. Handle RBN_CHILDSIZE notification (not really working)
* 6. Draw separators between bands and fix size of grippers.
* 7. Draw separators between rows.
* 8. Support RBBS_BREAK if specified by user.
* 9. Support background color for band and draw the background.
* 10. Eliminated duplicate code in SetBandInfo[AW] and InsertBand[AW].
* 11. Support text color and propagate colors from Bar to Band
* rev 2,3,4
* - Implement initial version of row grouping, row separators,
* text and background colors. Support additional messages.
* Support RBBS_BREAK. Implement ERASEBKGND and improve painting.
* rev 5
* 1. Support dragging by the Gripper for only left and right drags
* within a row. (5a)
* 2. Implement WM_LBUTTONDOWN, WM_LBUTTONUP, and WM_MOUSEMOVE.
* 3. Support RBS_BANDBORDERS.
* 4. Total rewrite of MouseMove code to handle multiple bands in row. (5b)
* 5. Fix drawing bugs.
*
* Still to do:
* 1. default row height should be the max height of all visible bands
* 2. Following still not handled: RBBS_FIXEDBMP, RBBS_CHILDEDGE,
