@englercj: I'm having issues rendering textures from a dataURI in IE 11 and Edge. Creating a texture from a png works fine in both. I've tried to run this with legacy set to true and false. I created a jsfiddle that uses Texture.fromImage() using a png and a data uri. It works fine in other browser, just not IE or Edge.
