.SH NAME
display-sub \- Make a child visual that is a window to the parent
.SH "DESCRIPTION"
.PP
Creates a `child' visual within a "parent". This can be thought of
as a window and the \fBsub\fR target is intended
for simple windowing systems.
.PP
No textual arguments. \fIargptr\fR must contain the parent
visual.
.PP
The sub target behaves a bit special with respect to (i.e. abuses the
semantics of :) the \fBggiSetMode\fR call. It uses the "visible" size for the top left corner
position of the window within the visual, and the "virtual" size for
window width and height. Note, that moving/resizing the window does
\fBnot\fR cause any drawing action. You have to perform those
yourself. All it does for you is providing a virtual visual within an
existing one, which is convenient to allow for window system canvases to
be about any GGI program.
.SH "FEATURES"
DirectBuffer not supported.
Accelerated to the point of the parent. Calls are mapped
through with modified clipping and coordinates.
