*
* GDI+ Image Attributes used with Graphics.DrawImage
*
* 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.
