 In some cases, the CAPI function `GEOSLength_r` returns `2` on error, when
 it is documented to return `0`. The `2` is likely to be interpreted as
 "success" by a caller.

 In some cases, the CAPI function `GEOSIsValidDetail_r` returns `0` on
 error, when it is documented to return `2`. The `0` would be falsely
 interpreted as "geometry invalid."
