It's cut like that when manufactured, but only straight cuts.

As the glass leaves the lehr annealer it's still in a continuous
ribbon, it's cut on the move by a traversing head - it's good to watch
as the glass is moving, the cutter moves diagonally to keep the cut
straight. It's sometimes cut again down the line into smaller sheets.

These cuts merely score the surface, the break is done mechanically.
(Differing conveyor levels - it snaps under its own weight or a
breaker bar - depending on size)

You "may" be able to do the fancy shapes using a spring loaded single
point diamond tool then breaking by hand, but unless your mass
producing the same design on flat glass, a good man with a wheel or
diamond will outperform you.

A lot of the stained glass stuff I've seen uses rough glass that is
difficult to cut by hand. Unless you were using some sort of laser
would be very difficult by machine.
