Previous policy (WHEN SIMPLE) turned out to be non-simple,
so this has been changed to TAINING.
Bbox will then be recomputed by scanning output coordinates
iff input had a bbox cache.
AUTOCACHE_BBOX define (the default) will still force a
computation of output box if worth it.
Regress tests added for the case reported on postgis-users
Run of regress tests do not require postgis install
anymore. The library build in source tree will be
used for this purpose.
Version bumped to 1.1.2 and CHANGES file updated.
