An identity palette is a palette where the colors and order of those colors match the physical palette.
Use the identity palette whenever possible, because if the system does not have to map colors, it can speed bitmap drawing.

| owl::TIdentityPalette::TIdentityPalette | ( | const TPalette & | palette | ) |
Implementation of Identity Palette object, TIdentityPalette.
Use of an identity palette allows objects to be blitted without having the color mapper come into play. The overall effect is faster graphics. Return an identity palette to be used by bitmaps. This ensures speed and color accuracy.
TH The passed color table should be indexed from the start not from
