NAME
SbVec2i32 -
The SbVec2i32 class is a 2 dimensional vector with short integer
coordinates.
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.

Constructor & Destructor Documentation
SbVec2i32::SbVec2i32 (void) [inline] The default constructor does nothing.
The vector coordinates will be uninitialized until you do a setValue().

instance with initial values from v.
SbVec2i32::SbVec2i32 (int32_t x, int32_t y) [inline] Constructs an
SbVec2i32 instance with the initial vector endpoints from x and y.
