FATAL ERROR: v8::ToLocalChecked Empty MaybeLocal.

[m-s-sh]

Hi,
in case FrameBuffer::FrameBuffer fails (I go that myself, but saw it also here) it will never show the right error message, because will be shadowed by

FATAL ERROR: v8::ToLocalChecked Empty MaybeLocal.

Reason for it is code in

Local<Object> FrameBuffer::NewInstance(Local<Value> arg, Local<Value> arg2)

you are using

.ToLocalChecked();

and it will fail in case object is null.
I think it needs to be replaced by the following

.FromMaybe(v8::Local<v8::Object>())

I can do the change if you also agree.

By the way throwing execution in constructor is not so good idea.
