This variable exists in CG only on the GTK platform (that is, not on
Windows). If needed, a #+gtk conditionalization
could be used with this variable.
The value of this variable indicates what happens on the GTK platform when application code calls a Common Graphics function that cannot be (or has not yet been) implemented to handle the call as documented.
The default value is :warn, which calls warn with
an informational message and then returns normally. Alternately the
value may be :error to signal an error, or nil to ignore the call and do nothing.
There may still be a significant number of cases that are not covered by this warning system, where either nothing will happen or a break will occur. Refer to cggtk-relnotes.html for complete information on CG differences on the GTK platform.
