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