Abstract super class of commands that simply draw on the acetate layer. The top-most layer. The
graphics object will be set just prior to the execution of the command and is used to execute
draw commands. Subclasses do not need to be concerned about resetting the graphics2D because the
RenderManager, which executes the command will handle the issue.
