1;;; test-shader-limits — the measured proof for sigil-graphics v0.11.3's

2;;; shader additions, on native and on the web build.

3;;;

4;;; One scene, two shells (the (crash main) seam): a Game of Life stepped

5;;; entirely on the GPU by render-target ping-pong with a shader bound

6;;; inside with-render-target, a palette drawn from `vec4 palette[8]` and

7;;; `float levels[4]` uniform arrays, and a 4x4 texture made from pixels

8;;; and refilled with update-texture. verify.mjs reads the presented frame

9;;; on both targets and asserts every cell, strip and texel.

10;;;

11;;; sigil deps install --redirects dev-redirects.sgl

12;;; sigil build --redirects dev-redirects.sgl native

13;;; sigil build --redirects dev-redirects.sgl --config web browser

14;;; node verify.mjs --native | --web (see README)
