For option 2:
The work is to convert 
void WebGLRenderingContextBase::texImageImpl(TexImageFunctionID functionID, GCGLenum target, GCGLint level, GCGLenum internalformat, GCGLint xoffset, GCGLint yoffset, GCGLint zoffset, GCGLenum format, GCGLenum type, Image* image, GraphicsContextGL::DOMSource domSource, bool flipY, bool premultiplyAlpha, bool ignoreNativeImageAlphaPremultiplication, const IntRect& sourceImageRect, GCGLsizei depth, GCGLint unpackImageHeight)

to run on GPU process side resources.

Essentially converting Image* image to GPU process side resource.

However, that function _also_ needs to stay mostly working with Web process side resources, since some of the cases are such that probably no reasonable GPU process side resource exist.
