From the X protocol glossary:

.LP
\fBViewable\fP
.IN "Viewable" "" "@DEF@"
.IP
A window is viewable if it and all of its ancestors are mapped.
This does not imply that any portion of the window is actually visible.
Graphics requests can be performed on a window when it is not viewable,
but output will not be retained unless the server is maintaining
backing store.
