shades the viewport in linear light: the key light and eye fill over a
sky fill that grows as a face turns up, plus the 4% of that sky every
dielectric reflects (a little more toward grazing), encoded to sRGB
once. Near-black faces keep a gradient; light and mid-grey faces stay
within a few levels of the sRGB shading. The world's up direction and
the switch ride in a new `sky` vec4 at the end of the viewport uniform,
and the frame key, so turning it on redraws. Off, the shader takes the
old path unchanged.
