Added a helper function emscripten_set_canvas_size function which allows to resize the <canvas> element on the web page in 'generic' fashion without having to depend on SDL or X11 headers in C code. This function is intended to be used in conjunction with EGL to specify a custom pixel resolution for the canvas (EGL API does not have expressiveness to do arbitrary pixel sizes).
