// base object for all swf-entities
//
// Notes
// - keeps underlying SWF entity handle, and adjustments
//
// - a translation / rotation / skew matrix is kept so that objects can
// be created with specific offset, rotation, etc
//
// - eval() is provided so that the object can be adjusted or rendered just
// prior to being added to a parent container (as in MC.add(object))
