Remove USE_DISPLAY_LIST_PROPERTIES flag

This flag was still hanging around pending any need to disable
DisplayList properties. But things seem stable, so it's time to clean up
and simplify the code.

At the same time, I reduced redundance in DisplayList dimensions. We
used to call drawDisplayList() with width/height parameters that were
used to do a clip reject. This is redundant with the DisplayList properties
that set the bounds of the DisplayList; the left/right and top/bottom properties
represent the same width/height properties formerly used in drawDisplayList().
The new approach is to not pass dimensions to drawDisplayList(), but to
instead pull those dimensions directly from the DisplayList when needed.
