8.3.3 Output Protocol Classes
The following classes implement the standard output protocols.
=> standard-sheet-output-mixin [Class]
This class is mixed in to any sheet that provides the standard output protocol, such as repainting
and graphics.
=> mute-sheet-output-mixin [Class]
This class is mixed in to any sheet that provides none of the output protocol.
=> permanent-medium-sheet-output-mixin [Class]
This class is mixed in to any sheet that always has a medium associated with it.
=> temporary-medium-sheet-output-mixin [Class]
This class is mixed in to any sheet that may have a medium associated with it, but does not
necessarily have a medium at any given instant.
8.3.4 Associating a Medium with a Sheet
Before a sheet may be used for output, it must be associated with a medium. Some sheets are
permanently associated with media for output efficiency; for example, CLIM window stream
sheets have a medium that is permanently allocated to the window.
However, many kinds of sheets only perform output infrequently, and therefore do not need
to be associated with a medium except when output is actually required. Sheets without a
