NAME
display-multi : Duplicate visual operations onto multiple visuals
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.
