Constants

The gemetry management classes make use of several constants:

• mred:const-default-position -- This constant can be passed in to various functions in place of a position argument to indicate that the object should be placed at its default position. Note that the idea of ``default position'' is platform dependant.
• mred:const-default-size -- This constant can be passed in to various functions in place of a size argument to indicate that the object should be given its default size (again, ``default size'' is platform dependant).
• mred:const-default-spacing -- This constant is the default size of the spacing between objects inside a panel.
• mred:const-default-border -- This constant is the default size of the border between objects in a panel and the edge of the panel.
