Add a second distance field adjust table that only applies contrast, not fake-gamma correction. Store a flag in the batch at creation time, using the same logic we apply elsewhere (render target format, plus paint flags). That gets us close, but not as good as bitmap text. The final step is to use a linear step function (rather than smoothstep) to map distance to coverage, when we have sRGB output. Smoothstep's nonlinear response is actually doing some fake-gamma, so it ends up over-correcting when the output is already gamma-correct. Results are now very close between L32 (old table, smoothstep) and S32 (contrast-only table, linstep).
