Started work on a quad-colorAttachment version of WGLFramebuffer. Also took out all branching in the shader programs. More confusing, but probably faster. Also changed the #extension usage in the normal-derivation shader to error out if the GL_OES_standard_derivatives extension is not available. Callbacks were also added for GLContext loss and restoration. They are untested at this point, however.
