Please see my earlier comments. In order to land this patch without breaking the
repository you'll need to (1) add a new overload of copyTextureCHROMIUM in the
subclasses; (2) add the new overload into WebGraphicsContext3D in the Blink
repository, switch over all code to call it, and delete the old overload; and
(3) delete the old copyTextureCHROMIUM overload.

 
   virtual void bindUniformLocationCHROMIUM(WebGLId program, WGC3Dint location,
                                            const WGC3Dchar* uniform);
