The Peek Button: Show Layer Composition

The Peek button in the View Menu asks the user to define a rectangular area with pointer clicks ar drag, and then redisplays the area slowly so that underlying layers can be seen. It also prints the names of layers found (only physical objects are considered, not labels). The delay, which defaults to .4 second per existing layer, can be reset with the PeekSleepMsec variable, which can be set to the delay time in milliseconds.
