Yes, here's 50372 thru 50402:

                  {
                        FT_Fixed  cond = args[0] && args[1];

                        FT_TRACE4(( " and\n" ));

                        args[0] = cond ? 0x10000L : 0;
                        args++;
                  }
                  break;

                case cff_op_or:
                  {
                        FT_Fixed  cond = args[0] || args[1];

                        FT_TRACE4(( " or\n" ));

                        args[0] = cond ? 0x10000L : 0;
                        args++;
                  }
                  break;

                case cff_op_eq:
                  {
                        FT_Fixed  cond = !args[0];

                        FT_TRACE4(( " eq\n" ));

                        args[0] = cond ? 0x10000L : 0;
                        args++;
                  }
                  break;

And here's 144801 thru 144810:

        /* we need to scale the values by 1.0/temp_scale */
        if ( temp_scale != 0x10000L )
        {
          temp[0] = FT_DivFix( temp[0], temp_scale );
          temp[1] = FT_DivFix( temp[1], temp_scale );
          temp[2] = FT_DivFix( temp[2], temp_scale );
          temp[4] = FT_DivFix( temp[4], temp_scale );
          temp[5] = FT_DivFix( temp[5], temp_scale );
          temp[3] = temp[3] < 0 ? -0x10000L : 0x10000L;
        }
