Use fabs() instead of abs() for non-integer variables in SVG DC

Browse Source 
::abs() truncates floating point values to ints, so use fabs() instead. This
could have been also corrected by using std::abs(), which is overloaded for
multiple types, but use fabs() for consistency with the existing code.

This fixes a problem introduced in 1e0719ad81.

See #17557.
