Without these dots, the glass could become loose and eventually fall out of the frame. These frits are also there for aesthetic purposes.

I thought the transition from pure black to window with dots was made for thermic reasons, so there is not a hard line between hot and cold glass, and with that less stress on the material.

The complete black border is probably for holding it to the glue, I suspect.
