So I can create the texture as a pixmap instead of a mipmap and it
generates the lower res textures for me...or I can use a mipmap but I have
to create and supply the downsampled textures manually.  Are both points
made correct so far?

If so, what is the advantage of mipmaps.  They require more work, so what
do they buy you?  Do they offer more control over when resolution is
switched, or more gradations of texture dimension?  Any advantage at all?
