/*
About LUMA_FP64_CODE_ELIMINATION_WORKAROUND

The purpose of this workaround is to prevent shader compilers from
optimizing away necessary arithmetic operations by swapping their sequences
or transform the equation to some 'equivalent' form.

These helpers implement Dekker/Veltkamp-style error tracking. If the compiler
folds constants or reassociates the arithmetic, the high/low split can stop
tracking the rounding error correctly. That failure mode tends to look fine in
simple coordinate setup, but then breaks down inside iterative arithmetic such
as fp64 Mandelbrot loops.

The method is to multiply an artifical variable, ONE, which will be known to
the compiler to be 1 only at runtime. The whole expression is then represented
as a polynomial with respective to ONE. In the coefficients of all terms, only one a
and one b should appear

err = (a + b) * ONE^6 - a * ONE^5 - (a + b) * ONE^4 + a * ONE^3 - b - (a + b) * ONE^2 + a * ONE
