- MODULE R_CONSTANTS
-
- This module sets up all the constants used in this functional
- animation package.
- Defined here are the basic units of movement, scale and rotation.
- The screen height and width are set, and the various parts of
- the screen such as the top-middle, lower-left and center are
- all set. Finally the color values used by xcshow, the c-program
- that displays the movies in X, are set.
