Duplicate visual operations onto multiple visuals
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

.. manpage:: 7 display-multi


Synopsis
--------

::

  display-multi <:targetspec> ...


Description
-----------


Duplicates all drawing operations onto multiple *child* targets, thus
producing identical output on multiple visuals.


Options
-------

The argument to `display-multi` is a colon- (``:``) separated list of
target specs to draw on.  Because target specs can (and often do)
contain colons, they need to be enclosed in parentheses.


Features
--------


- DirectBuffer never supported.
- Unaccelerated.
