Comment (by mdavis):

 That wagyu quick clip algorithm will certainly be fast. But it will
 produce highly invalid geometry from a GEOS geometry model perspective.
 That may not matter for tile rendering, of course.

 But then it's doing something different than GEOSClipByRect, which is
 intended to produce valid geometry.  This is a harder task, so slower and
 more demanding of the input.

 If MVT Tile generation can get away with a less restrictive geometry model
 and hence faster/simpler algorithms, that's great. But perhaps those
 algorithms should not be in GEOS, or at least they should be in a separate
 package.
