#4294: ST_AsMVTGeom: Do resolution check before deserializing
-------------------------+---------------------------

-------------------------+---------------------------
 In #4161 I added a shortcut to drop small lines and polygons before any
 call to the simplification process. I've now noticed that this check could
 be done before deserializing the geometry since all you need is the
 geometry type and bounding box.

 I'll try to move this check to `ST_AsMVTGeom` (C function) before the
 `lwgeom_from_gserialized` call and measure its impact in this kind of
 input.
