-\func{void}{SetOptimization}{\param{bool }{optimize}}
-
-If {\it optimize} is true (the default), this function sets optimization mode on.
-This currently means that under X, the device context will not try to set a pen or brush
-property if it is known to be set already. This approach can fall down
-if non-wxWidgets code is using the same device context or window, for example
-when the window is a panel on which the windowing system draws panel items.
-The wxWidgets device context 'memory' will now be out of step with reality.

-Setting optimization off, drawing, then setting it back on again, is a trick
-that must occasionally be employed.
