// There are 5 possible sets of color adjustments:
// ColorAdjustDefault,
// ColorAdjustBitmap,
// ColorAdjustBrush,
// ColorAdjustPen,
// ColorAdjustText,
// Bitmaps, Brushes, Pens, and Text will all use any color adjustments
// that have been set into the default ImageAttributes until their own
// color adjustments have been set. So as soon as any "Set" method is
// called for Bitmaps, Brushes, Pens, or Text, then they start from
// scratch with only the color adjustments that have been set for them.
// Calling Reset removes any individual color adjustments for a type
// and makes it revert back to using all the default color adjustments
// (if any). The SetToIdentity method is a way to force a type to
// have no color adjustments at all, regardless of what previous adjustments
// have been set for the defaults or for that type.
