/**
 * ComponentAdapter for a JXMonthView (experimental for internal use of BasicMonthViewUI).
 * 
 * For now, this effectively disables all notion of row/column coordinates. It's focused
 * on an externally provided date (as Calendar) and CalendarState. Yeah, I know, that's
 * tweaking too much but then, I want to use highlighters which need an adapter...
