*
* * CALC_PUSH_NUMBER (N)
*   - takes a css_fixed and pushes it onto the operand stack
* * CALC_PUSH_VALUE (V)
*   - takes a css_fixed and a unit, and pushes them
* * CALC_{ADD,SUBTRACT,MULTIPLY,DIVIDE} (+ - * /)
*   - pop two values, perform the operation, push the result
* * CALC_FINISH (=)
*   - pop the top value from the stack and return it.
