| * WIN_HaveToDelayNCPAINT |
| * |
| * Currently, in the Wine painting mechanism, the WM_NCPAINT message |
| * is generated as soon as a region intersecting the non-client area |
| * of a window is invalidated. |
| * |
| * This technique will work fine for all windows whose parents |
| * have the WS_CLIPCHILDREN style. When the parents have that style, |
| * they are not going to override the contents of their children. |
| * However, when the parent doesn't have that style, Windows relies |
| * on a "painter's algorithm" to display the contents of the windows. |
| * That is, windows are painted from back to front. This includes the |
| * non-client area. |
| * |
| * This method looks at the current state of a window to determine |
| * if the sending of the WM_NCPAINT message should be delayed until |
| * the BeginPaint call. |
| * |
| * PARAMS: |
| * wndPtr - A Locked window pointer to the window we're |
| * examining. |
| * uncFlags - This is the flag passed to the WIN_UpdateNCRgn |
| * function. This is a shortcut for the cases when |
| * we already know when to avoid scanning all the |
| * parents of a window. If you already know that this |
| * window's NCPAINT should be delayed, set the |
| * UNC_DELAY_NCPAINT flag for this parameter. |
| * |
| * This shortcut behavior is implemented in the |
| * RDW_Paint() method. |
