Also:
* optimize the ds2 terrain gimmick (ds2_11)
* use golden ratio + blue noise on marched fog
* add second sun to analytic fog
* fix gcd() implementation
* add faster rand2() implementation

Simple algo. Use quad intrinsics to get neighboring pixels' (x & y)
positions in trochoid space. Compute tangent and bitangent from that.
Then normal as cross product. There's some artifacting on diagonal
boundaries.

Seems like the determinant of the jacobian is ~0, meaning it's not
invertible. That means the normals look fucked up.

attempt to fix hypotrochoid normals
key insight is that multiplying normal by transpose(invert(jacobian)) of
transform should work, but it fucking doesn't

This should solve the issue of Unity failing to fully recompile my
fucking shader.

Trochoid is a WIP. Need to do some magic to make it properly shear. In
short: it's currently implemented as a standalone Mesh Renderer object
which I place on my avatar's neck bone. Since its object origin is not
at the hip bone like everything else, it behaves weirdly when shearing.
Solution is to implement it as a regular skinned mesh renderer. Requires
some careful analysis to get right.
