 * 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.
