\brief The SbVec2i32 class is a 2 dimensional vector with short integer
coordinates.
\ingroup base
This vector class is used by many other classes in
Coin. It provides storage for a vector in 2 dimensions
as well as simple integer arithmetic operations.
\sa SbVec2f, SbVec2d, SbVec3s, SbVec3f, SbVec3d, SbVec4f, SbVec4d.
