Style constant for no background behavior (value is 1<<18).
<p>
By default, before a widget paints, the client area is filled with the current background.
When this style is specified, the background is not filled, and the application is responsible
for filling every pixel of the client area.
This style might be used as an alternative to "double-buffering" in order to reduce flicker.
This style does not mean "transparent" - widgets that are obscured will not draw through.
