This javascript webapp converts GLSL code from shadertoy.com to Gamemaker GLSL ES as well as output other necessary code to run.

## What does it do?

* Adds ```varying vec2 fragCoord;```

* Replaces ```void MainImage()``` with ```void main(void)```.

* Replaces ```fragColor``` with ```gl_FragColor```.

* Replaces all instances of ```texture``` to ```texture2D```.

* Replaces all instances of ```iChannel0``` to ```gm_BaseTexture```.

* Replaces all instances of ```iTime``` to ```iGlobalTime```.

* Adds ```uniform vec3 iResolution;``` if ```iResolution.xy``` is found, else...

* ...Adds ```uniform float iResolution;``` if ```iResolution``` is found

* Adds ```uniform float iGlobalTime;```.

* Edits the pow(x, y) function to pow(abs(x), y)

* Outputs vertex, fragment, create event, and draw event.

* Warns of incompatible commands.

This works for simple shaders. More complex shaders require more manual work on your part.
