257About LUMA_FP64_CODE_ELIMINATION_WORKAROUND
258
259The purpose of this workaround is to prevent shader compilers from
260optimizing away necessary arithmetic operations by swapping their sequences
261or transform the equation to some 'equivalent' form.
262
263These helpers implement Dekker/Veltkamp-style error tracking. If the compiler
264folds constants or reassociates the arithmetic, the high/low split can stop
265tracking the rounding error correctly. That failure mode tends to look fine in
266simple coordinate setup, but then breaks down inside iterative arithmetic such
267as fp64 Mandelbrot loops.
268
269The method is to multiply an artifical variable, ONE, which will be known to
270the compiler to be 1 only at runtime. The whole expression is then represented
271as a polynomial with respective to ONE. In the coefficients of all terms, only one a
272and one b should appear
273
274err = (a + b) * ONE^6 - a * ONE^5 - (a + b) * ONE^4 + a * ONE^3 - b - (a + b) * ONE^2 + a * ONE
