The ShaderLoader uses AJAX to asychronously load external shader files included in the DOM as script elements using the format:

<script data-src="shaders/name/vertex.js"
	data-name="myShader"
	type="x-shader/x-vertex"></script>

<script data-src="shaders/name/fragment.js"
	data-name="myShader"
	type="x-shader/x-fragment"></script>

Where:

	data-src: Path to the shader file
	data-name: Name of the shader to be used as key in the load object
	type: Shader type ["x-shader/x-vertex" | "x-shader/x-fragment"]

When all loading has completed it will attempt to invoke the passed in onShadersLoaded callback with a parameter "data" containing all loaded shaders.

Callback signature:

function onShadersLoaded(data)
{
	// Do stuff with "data" load object
}

Shaders load object structure:

data = {
	"name from data-name": {
		vertex: "...",
		fragment: "..."
	},
	{...}
};

Example Usage:

[index.html]:

	<script data-src="shaders/particles/vertex.js" data-name="particles"
			type="x-shader/x-vertex"></script>
	<script data-src="shaders/particles/fragment.js" data-name="particles"
		type="x-shader/x-fragment"></script>

	<script data-src="shaders/world/vertex.js" data-name="world"
			type="x-shader/x-vertex"></script>
	<script data-src="shaders/world/fragment.js" data-name="world"
		type="x-shader/x-fragment"></script>

[example.js]:

	SHADER_LOADER.load(
		function (data)
		{
			var particlesVertexShader = data.particles.vertex;
			var particlesFragmentShader = data.particles.fragment;

			var worldVertexShader = data.world.vertex;
			var worldFragmentShader = data.world.fragment;
		}
	);
