OEReadShapeQuery overload has been added to work on
oeistream objects instead of a direct file name.
OEOverlap.SetGridSpacing has been added to allow
adjusting the grid spacing used by the
OEOverlapMethod_Grid shape overlap
method. Lower values typically yield overlaps that agree more
closely with the OEOverlapMethod_Exact method,
while higher values can sometimes be faster and will diverge more.
OEBOOrientation_Subrocs will sometimes crash
when given a grid as the reference. Some of these crashes have been
fixed, but others are more difficult to pin down and will persist
till the next release.
