/**
* This is a hack around DefaultTableCellRenderer color "memory",
* see Issue #258-swingx.
*
* The issue is that the default has internal color management
* which is different from other types of renderers. The
* consequence of the internal color handling is that there's
* a color memory which must be reset somehow. The "old" hack around
* reset the xxColors of all types of renderers to the adapter's
* target XXColors, introducing #178-swingx (Highlighgters must not
* change any colors except those for which their color properties are
* explicitly set).
*
* This hack limits the interference to renderers of type
* DefaultTableCellRenderer, applying a hacking highlighter which
* resets the renderers XXColors to a previously "memorized"
* color. Note that setting the color to null didn't have the desired
* effect.
*
* PENDING: extend ColorHighlighter
