Funny how pictures circulate around the web.
I did that job (my picture) in the Philly area back in 2004 for a PA state trooper. Great guy, took me to lunch every day.
The bevel was so slight I didn't taper the 45 degree angle cuts at all. I may have just cut the outside border of the frame to make it a square edge..not quite sure.
How were the perfect cuts achieved? Just like Kevin mentioned, the picture frame installed first, then all individual boards cut to fit..individually. They'll all never be exactly 45 degrees. In fact I think most were 46 degrees (plus or minus) because I started the entire job some 800 square feet away from the hearth...in another room.

All were routed, splined and glued. The hardest cut was the intersection at the corner of the hearth where I probably did it free hand with a table saw because jig or sabre saw cuts don't offer as clean a cut.
Price? It was in the bundle on this one.
