00047 * The range slider widget is a valuator widget which determines a subrange of the
00048 * given range.  It has two heads, one for the lower and one for the upper range.
00049 * Two visual appearances are supported:- the sunken look, which is enabled with
00050 * the RANGESLIDER_INSIDE_BAR option and the regular look.  The latter may have optional
00051 * arrows on the slider thumb.
00052 * While being moved, the slider sends a SEL_CHANGED message to its target;
00053 * at the end of the interaction, a SEL_COMMAND message is sent.
00054 * The message data represents the current slider value, a pointer to an array
00055 * of two FXint's, representing the values of the lower and upper positions.
