* Basic type used for the geometry classes. By making it a typedef we can
* easily change it in the future.
*
* All coordinates are maintained as signed 32-bit integers in the twips
* coordinate space. A twip is 1/20th of a point, and there are 72 points per
* inch.
*
* Twips are used because they are a device-independent unit of measure. See
* header file nsUnitConversion.h for many useful macros to convert between
* different units of measure.
