Fixes #1155
The “Optimizing WebGL Sketches” tutorial used
heightinstead ofwidthwhen converting 2D coordinates to the 1Dpixels[]array.This worked only because the example canvas was square. The code has been updated to use the correct pixel indexing formula, matching the p5.js reference documentation.
No other behavior or examples were changed.
