I would prefer an explicit "if (!draw_hdc && !read_hdc) { /* clear context->draw_... */ } else" be introduced before the "if ((hwnd = WindowFromDC(draw_hdc)))".

First, from my reading of the spec, a NULL draw_hdc and a non-NULL read_hdc should still be an error.  Second, burying the logic in the pbuffer branch seems obscure.
