/* The basic ideas here are:
* 2.0 * +/-INF == +/-INF
* NAN != NAN
*
* The vertex shader value is written to the red component, with 0.0
* and +/-INF mapping to 0xff, and NAN to 0x7f. Anything else should
* result in 0x00. The pixel shader value is written to the green
* component, but here 0.0 also results in 0x00. The actual value is
* written to the blue component.
*
* There are at least two different ways for D3D implementations to
* handle this. AMD seems to stick mostly to the D3D documentation,
* and doesn't generate floating point specials in the first place.
* Note that that doesn't just apply to functions like rcp and rsq,
* but also basic mul, add, etc. nVidia seems to generate infinities,
* but then clamp them before sending them to the interpolators. In
* OpenGL these aren't clamped, and interpolating them generates NANs
* in the fragment shader, unless flat shading is used (essentially
* replicating the values instead of interpolating them).
*
* I can't currently explain the nVidia results for pow and nrm.
* They're not specials in the vertex shader, but look like -INF in
* the pixel shader. */
