Display a WebGL shader.

== Description ==

This plugin allows you to display a WebGL2 fragment shader, compatible with https://shadertoy.com

Simply copy and paste the code of your fragment shader into the edit box.

This plugin makes use of the open source "gl-matrix" library by Brandon Jones and Colin MacKensie IV.

Your shader code should look like the example below.  The mainImage() function is called once for each pixel.

```
void mainImage(out vec4 fragColor, in vec2 fragCoord)
{
    // Normalized pixel coordinates (from 0 to 1).
    vec2 uv = fragCoord / iResolution.xy;

    // Output to screen as (r, g, b, alpha).
    fragColor = vec4(uv.x, uv.y, 0.0, 1.0);
}
```

== Installation ==

1. Upload the plugin files to the `/wp-content/plugins/display-webgl-shader` directory, or install the plugin through the WordPress plugins screen directly.
1. Activate the plugin through the 'Plugins' screen in WordPress
