    engine: polymer: 'fix' texture scale on relative floors
    
    Classic relative scaling apparently had some numerical artifacts related
    to length of firstwall. Cribbing the logic added in 6fc6b7d5 in Polymost
    along with bumping the precision of the intermediate terms seems to make
    it line up fully. Rooftop floor in E1L1 and surrounding ledges are good
    test cases for this.
