+ * @author yomboprime https://github.com/yomboprime
+ *
+ * GPUComputationRenderer, based on SimulationRenderer by zz85
+ *
+ * The GPUComputationRenderer uses the concept of variables. These variables are RGBA float textures that hold 4 floats
+ * for each compute element (texel)
+ *
+ * Each variable has a fragment shader that defines the computation made to obtain the variable in question.
+ * You can use as many variables you need, and make dependencies so you can use textures of other variables in the shader
+ * (the sampler uniforms are added automatically) Most of the variables will need themselves as dependency.
+ *
+ * The renderer has actually two render targets per variable, to make ping-pong. Textures from the current frame are used
+ * as inputs to render the textures of the next frame.
+ *
+ * The render targets of the variables can be used as input textures for your visualization shaders.
+ *
+ * Variable names should be valid identifiers and should not collide with THREE GLSL used identifiers.
+ * a common approach could be to use 'texture' prefixing the variable name; i.e texturePosition, textureVelocity...
+ *
+ * The size of the computation (sizeX * sizeY) is defined as 'resolution' automatically in the shader. For example:
+ * #DEFINE resolution vec2( 1024.0, 1024.0 )
+ *
+ * -------------
+ *
+ * Basic use:
+ *
+ * // Initialization...
+ *
+ * // Create computation renderer
+ * var gpuCompute = new GPUComputationRenderer( 1024, 1024, renderer );
+ *
+ * // Create initial state float textures
+ * var pos0 = gpuCompute.createTexture();
+ * var vel0 = gpuCompute.createTexture();
+ * // and fill in here the texture data...
+ *
+ * // Add texture variables
+ * var velVar = gpuCompute.addVariable( "textureVelocity", fragmentShaderVel, pos0 );
+ * var posVar = gpuCompute.addVariable( "texturePosition", fragmentShaderPos, vel0 );
+ *
+ * // Add variable dependencies
+ * gpuCompute.setVariableDependencies( velVar, [ velVar, posVar ] );
+ * gpuCompute.setVariableDependencies( posVar, [ velVar, posVar ] );
+ *
+ * // Add custom uniforms
+ * velVar.material.uniforms.time = { value: 0.0 };
+ *
+ * // Check for completeness
+ * var error = gpuCompute.init();
+ * if ( error !== null ) {
+ * console.error( error );
+ * }
+ *
+ *
+ * // In each frame...
+ *
+ * // Compute!
+ * gpuCompute.compute();
+ *
+ * // Update texture uniforms in your visualization materials with the gpu renderer output
+ * myMaterial.uniforms.myTexture.value = gpuCompute.getCurrentRenderTarget( posVar ).texture;
+ *
+ * // Do your rendering
+ * renderer.render( myScene, myCamera );
+ *
+ * -------------
+ *
+ * Also, you can use utility functions to create ShaderMaterial and perform computations (rendering between textures)
+ * Note that the shaders can have multiple input textures.
+ *
+ * var myFilter1 = gpuCompute.createShaderMaterial( myFilterFragmentShader1, { theTexture: { value: null } } );
+ * var myFilter2 = gpuCompute.createShaderMaterial( myFilterFragmentShader2, { theTexture: { value: null } } );
+ *
+ * var inputTexture = gpuCompute.createTexture();
+ *
+ * // Fill in here inputTexture...
+ *
+ * myFilter1.uniforms.theTexture.value = inputTexture;
+ *
+ * var myRenderTarget = gpuCompute.createRenderTarget();
+ * myFilter2.uniforms.theTexture.value = myRenderTarget.texture;
+ *
+ * var outputRenderTarget = gpuCompute.createRenderTarget();
+ *
+ * // Now use the output texture where you want:
+ * myMaterial.uniforms.map.value = outputRenderTarget.texture;
+ *
+ * // And compute each frame, before rendering to screen:
+ * gpuCompute.doRenderTarget( myFilter1, myRenderTarget );
+ * gpuCompute.doRenderTarget( myFilter2, outputRenderTarget );
+ *
+ *
+ *
+ * @param {int} sizeX Computation problem size is always 2d: sizeX * sizeY elements.
+ * @param {int} sizeY Computation problem size is always 2d: sizeX * sizeY elements.
+ * @param {WebGLRenderer} renderer The renderer
