Dynamically sort the effect slots when mixing
...
This is to be able to support effects that output to other effects. When an
effect outputs to another effect, the former needs to process first, so the
former mixes to the latter's buffer before the latter is processed.
This sorting needs to happen in the mixer because the effect slot's "Target"
property changes asynchronously.

Reorder some math terms to help optimizations
...
Because floating-point math is not associative ((a*b)*c does not necessarily
give the same result as a*(b*c)), the ordering of terms can inhibit reuse of
temporary values. For example, both
coeffs[9] = 2.091650066f * y * (3.0f*x*x - y*y);
and
coeffs[15] = 2.091650066f * x * (x*x - 3.0f*y*y);
contain x*x and y*y terms that could be calculated once, stored in temporary
registers, and reused to multiply with 3. But since 3.0f*(x*x) would produce
different results, the compiler is not allowed to make that optimization. If,
however, the multiply with 3 is moved to the right side:
coeffs[9] = 2.091650066f * y * (x*x*3.0f - y*y);
and
coeffs[15] = 2.091650066f * x * (x*x - y*y*3.0f);
in both cases x*x and y*y are calculated first in their respective groups,
guaranteeing the same results for both instances prior to the multiply with 3
and allowing the compiler to reuse those intermediate values.
