mipmap data structure

[Keith W. <kw...@cs...>]

The QD3D manual doesn't explain clearly *how* a mipmap is organized.  I
have made mipmaps with a single texture by providing a pixel buffer to the
image parameter and setting useMipmapping to false.  To use mipmapping I
set that to true of course.  Presumably, I need to fill in the mipmaps
array with width, height, and rowBytes that decrease by a factor of two
from the original texture until a size 1 is reached.

I am not sure what the offset parameter is or where the lower res pixel
buffers are stored.  There is only the one image parameter.

If I were to guess, I would say that each subsequent lower res texture is
appended to the image pixel buffer, and the offset for each is from the
beginning of the image buffer, but I have not documentation on this.

Am I right?
