The color depth of the image, in bits per pixel.
<p>
Note that a depth of 8 or less does not necessarily
mean that the image is palette indexed, or
conversely that a depth greater than 8 means that
the image is direct color. Check the associated
PaletteData's isDirect field for such determinations.
