On https://webgl2fundamentals.org/webgl/lessons/webgl-less-code-more-fun.html, one of the example `gl.vertexAttributePointer()` calls, the one for `a_texcoordLoc`, is missing the boolean "normalized" param: ``` // Setup all the buffers and attributes (assuming you made the buffers already) ... gl.vertexAttribPointer(a_positionLoc, positionNumComponents, gl.FLOAT, false, 0, 0); ... gl.vertexAttribPointer(a_normalLoc, normalNumComponents, gl.FLOAT, false, 0, 0); ... gl.vertexAttribPointer(a_texcoordLoc, texcoordNumComponents, gl.FLOAT, 0, 0); ```
