The DecreaseCalendarGlyph property allows you to define bitmap glyph to represent
the decrease calendar cell in the navigation section of the calendar header.
A bitmap defined in this property will override the DecreaseCalendarCaption property.
The bitmap will be centered in the decrease calendar cell. If the bitmap
height exceeds the FixedRowHeight property, the bitmap will be drawn from
the top of the decrease calendar cell. Similarly, if the bitmap width
exceeds the DayCellWidth property, the bitmap will be drawn from the left
of the decrease calendar cell.
NOTE: The ShowMonthButtons property must be enabled to see the decrease calendar glyph or caption.
