    Sort out abs/fabs confusion.
    
    My Mac has just upgraded itself to include a version of clang which
    warns if you use abs() on a floating-point value, or fabs() on an
    integer. Fixed the two occurrences that came up in this build (and
    which were actual build failures, because of -Werror), one in each
    direction.
    
    I think both were benign. The potentially dangerous one was using abs
    in place of fabs in grid_find_incentre(), because that could actually
    lose precision, but I think that function had plenty of precision to
    spare (grid point separation being of the order of tens of pixels) so
    nothing should have gone seriously wrong with the old code.
