PostGIS Box2D (and && operator) gives wrong result for ST_CircularString type

Reported by: vince Owned by: pramsey
Priority: medium Milestone: PostGIS 2.0.0
Component: postgis Version: master
Keywords: Box2D ST_Curve boxes Cc:

Description

Box2D is supposed to support ST_Curve types, but obviously, albeit calling Box2D with an ST_CircularString causes no error, the returned box is wrong. See three cases in the SQL sample file attached (circle, half-circle, "half-infinity" glyph).

Consequently, the && operator is also buggy, which prevent spatial queries to work reliably.

Seems same bugs exist in trunk (tested by Olivier Courtin, OsLandia).
