This method, which should ONLY be called from the execute() method
of a command, suspends processing of further queued commands until
the display of the show has caught up with the screen.
This method can be overridden by subclasses that want to look
for xlet arguments in places other than the default
XletContext.ARGS and "dvb.caller.parameters".
Scale the x, y, width and heigh values according to the current
values of SCALE_X_FIELD, SCALE_Y_FIELD, SCALE_X_FACTOR_FIELD
and SCALE_Y_FACTOR_FIELD, storing them in scaledBounds.

Variable in class com.hdcookbook.grin.features.Box
This should not be directly called by clients of the GRIN
framework, unless it is done from the animation thread (within
a command body, or inside an implementation of Director.nextFrame()).
Flags that some of the pixels in the area to be drawn might
be transparent or semi-transparent, either because they're
not drawn to, or because
they're drawn to in SrcOver mode.
