/*
* Rebar control rev 5b
*
* Copyright 1998, 1999 Eric Kohl
*
* NOTES
* An author is needed! Any volunteers?
* I will only improve this control once in a while.
* Eric <ekohl@abo.rhein-zeitung.de>
*
* TODO:
* - vertical placement
* - ComboBox and ComboBoxEx placement
* - center image
* - Layout code.
* - Display code.
* - Some messages.
* - All notifications.
* Changes Guy Albertelli <galberte@neo.lrun.com>
* 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,
* RBBS_VARIABLEHEIGHT, RBBS_USECHEVRON
* 3. GETBANDINFO seems to return correct colors in native but not here.
