* systems. This is effectively a type-safe float, intended to be used in
* combination with the known-type instances of gfx::Point, gfx::Rect, etc.
*
* Note that some parts of the code that pre-date this class used separate
* scaling factors for the x and y axes. However, at runtime these values
* were always expected to be the same, so this class uses only one scale
* factor for both axes. The two constructors that take two-axis scaling
* factors check to ensure that this assertion holds.
* This class is meant to be used in cases where a single scale applies to
* both the x and y axes. For cases where two diferent scales apply, use
* ScaleFactors2D.
