Remarks
This class is helpful for use with terrain providers where the possible range of heights is substantially larger than the common range of heights. For example, the UsgsDigitalElevationModel terrain format specifies that heights are 32-bit integers. However, for all practical purposes, the heights don't exceed the bounds of a 16-bit integer. Using this type to store the posts for the UsgsDigitalElevationModel terrain provider allows us to get the space and performance advantages of storing posts as 16-bit integers, while still supporting the rare terrain file that actually requires 32-bit integers.
