* Add Vector2d classes that represent offsets, instead of using Point.danakj@chromium.org2012-10-311-0/+186
Previously Point served two purposes, to be a position in 2d space, and also an offset from the origin. This introduces a Vector2d class to represent an offset, allowing typesafety checks for geometric operations. The following are now the case: Point +/- Vector = Point - A point plus/minus an offset gives you a point at a position offset by the vector. Vector +/- Vector = Vector - Two offsets can be added together to make a new offset. Point - Point = Vector - Subtracting one point from another gives you the offset between the two points. We add some new methods to perform these operations: Rect::OffsetFromOrigin() gives the offset between the position of the rect and the origin. Point::OffsetFromOrigin() gives the offset between the point and the origin. PointAtOffsetFromOrigin(Vector2d) converts a Vector2d to a Point at the given offset away from the origin. Rect::Offset(), Point::Add(), and Point::Subtract() now receive a Vector2d instead of a point.
