KMLSuperOverlay bounding box variant <gx:LatLonQuad> not supported

[cgodkin]

The function KmlSuperOverlayGetBoundingBox() doesn't deal with <gx:LatLonQuad>. I don't see a simple way to suggest a patch to this function to support it since it would appear to need some sort of warping on the fly because the gx:LatLonQuad is not necessarily a rectangle.

Attached will be an example of a dataset with this sort of bounding box.

GDAL 2.0-dev gives this:

ogrinfo -al -so s523_dtm.kmz
ERROR 1: ERROR Parseing kml Style: No id
INFO: Open of `s523_dtm.kmz'
      using driver `LIBKML' successful.

Layer name: 0
Geometry: Unknown (any)
Feature Count: 1
Extent: (-86.051901, 41.065544) - (-86.046436, 41.069912)

I do not know if the meaning of "doesn't deal with" was that GDAL can't read the bounding box at all or that GDAL reports wrong bounding box. If it was the first one, now GDAL obviously can read the bounding box and ticket can be closed as solved. It the latter (wrong bounding box) it would be nice to know the correct bounding box.
