Use.GPU - SDF + Font glyph renderer

• rust/wasm ab_glyph wrapper
• subpixel distance transform in TS

Stand-alone SDF:

import { glyphToSDF, rgbaToSDF } from '@use-gpu/glyph/sdf';

// Convert grayscale glyph to SDF
glyphToSDF = (
  data: Uint8Array,
  w: number,
  h: number,
  pad: number = 4,
  radius: number = 3,
  cutoff: number = 0.25,

  // ESDT vs EDT
  subpixel: boolean = true,

  // Solidify semi-transparent areas
  solidify: boolean = true,

  // Pre-process contour
  preprocess: boolean = false,

  // Post-process SDF
  postprocess: boolean = false,

  // Get intermediate steps
  debug?: (image: Image) => void,
): Image;

// Convert RGBA image to SDF
rgbaToSDF = (
  data: Uint8Array,
  w: number,
  h: number,
  pad: number = 4,
  radius: number = 3,
  cutoff: number = 0.25,
  subpixel: boolean = true,
  solidify: boolean = true,
  preprocess: boolean = false,
  postprocess: boolean = false,
  debug?: (image: Image) => void,
): Image;

type Image = {
  data: Uint8Array,
  width: number,
  height: number,
};
