Tested by running safetynet_compare.py on this patch vs master. The
results were 0 regressions and 0 improvements. The two remaining usages
cannot be replaced because they would cause a regression.

This existing code has the potential for an integer overflow in it.
When overflow occurs in this function scaling may partially succeed.
This is due to how out of range values are being clamped, which
implicitly swallows the overflow.
This CL changes the calculation to be performed in a 64-bit space and
then attempts to down cast it back to 32-bit space at the end. Because
there are multiple steps it is possible for an intermediate value to
cause an overflow in 32 bit space, but the final value to be valid. If
the downcast is not possible then the stretch operation is failed.
An existing test case has been updated, since it encoded an incorrect
result.

Make Copy() take a const-ref parameter. As is, the parameter is a
pointer and it is dereferenced without any checks, and there are no
crash reports as a result of that.
Also mention GetPattern() should only be called when IsPattern() returns
true.

It has no overrides and always returns the identity matrix. Many callers
that use the returned value can be simplified, because they are scaling
by 1 or concatenating an identity matrix.
