Graphic LCD Command Sheet HTML Version

Yet again I was looking for the GLCD command sheet in the internet and failed to find any good resolution images that I can use for post references. Even the data sheet looks really bad. So here I am with a HTML Version of the GLCD command sheet just like the one for the character LCD I posted a while back.
