- * but this means we need to rescale on both axes, which
- * yield unnecessary ugly texture. Also, same issues as 1)
- * b) rescale the biggest LOD in place and go two ways:
- * - update texImage->Width and texImage->Height, then
- * decrease maxLevel, so we won't rescale again on the
- * next validation. Changing texImage-> parameters is
- * not quite legal here (see convolution), but...
- * - leaving texImage-> parameters alone, while rescaling
- * texture and decreasing maxLevel makes Mesa puke. Also
- * this approach requires that mml->[wh]Scale go below 1,
- * otherwise bad ju-ju will be in our future (see fetch_texel)
- * Will this interfere with GL_TEXTURE_MAX_LEVEL? How?
- * The above approach is somehow dumb! we might have rescaled
- * once in TexImage2D to accomodate aspect ratio, and now we
- * are rescaling again. The thing is, in TexImage2D we don't
- * know whether we'll hit 1) or 2) by the time of validation.

- *
- * Which brings me to another issue. How can we handle NPOT textures?
- * - rescaling NPOT to the next bigger POT (mml->[wh]Scale can't shift)
- * - upping the max LOD to the next power-of-two, in fxTexGetInfo; then
