Details
This is a generic function with methods for grob and gTree objects.
The grob and gTree methods automatically push any viewports in a vp slot and automatically apply any gpar settings in a gp slot. In addition, the gTree method pushes and ups any viewports in a childrenvp slot and automatically calls grid.draw for any grobs in a children slot.
The methods for grob and gTree call the generic hook functions preDrawDetails, drawDetails, and postDrawDetails to allow classes derived from grob or gTree to perform additional viewport pushing/popping and produce additional output beyond the default behaviour for grobs and gTrees.
Value
None.
