usage

var shader = glShader.loadShader(gl, "shader.vert","shader.frag");

//note this is an asyncronous load, you must check that it has compiled before using

shader.begin();

//set a uniform in the shader
//replaces gl.uniform3fv(gl.getUniformLocation(shader,"someVector"),[1.0,0.0,0.0]);
shader.uniforms.someVector.set([1.0,0.0,0.0]);

//point a vertex attribute at a buffer
//replaces
//gl.bindBuffer(gl.ARRAY_BUFFER,buffer)
//gl.vertexAttribPointer(gl.getAttribLocation(shader,"vertexAttribute"),3,gl.FLOAT, gl.false,0,0);
shader.attribs.vertexAttribute.set(buffer);

//pointer method offers a little more flexibility allowing to input type, stride, and offset
gl.bindBuffer(gl.ARRAY_BUFFER,buffer2);
shader.attribs.otherAttribute.pointer(gl.UNSIGNED_SHORT, gl.FALSE,0,12);

//now draw something with your method of choice

shader.end();
