def lsst.skypix.quadsphere.imageToPolygon (   wcs,
  widthPix,
  heightPix,
  padRad = 0.0 
)
Computes and returns a spherical convex polygon approximation to the
region of the unit sphere covered by an image specified with a WCS and
a width/height (pixels). The polygon is computed by connecting the 
world coordinates of the 4 image corners with great circles, and can
optionally be padded by padRad radians.
