changelog:
Reduced the time for a window with many child windows to be displayed.
More info:
A large application was taking up to 10 seconds to display its main window. This appears to be due to X individually exposing every child window (of which there are very many) of the main application window and then wine forcing a redraw on the parent of every child and then all the subchildren again (!) resulting in the accumulation of a huge redraw list. This patch will force a redraw only on the child and not the parent as X will eventually expose that anyway. After applying this patch the initial redraw dropped from around 10 seconds to about 2 seconds and I could not find any painting problems
If anyone else is having slow application loading problems of this nature, then please try this patch.
