What happened to `setFontType` command?

I'm upgrading from 1.5.3. to 2.1.1, suddenly my code breaks because setFontType is no longer a thing... but there's nothing in the docs about this change that I can find.

So what do I do?

I have this:

this.doc = new jsPDF();
this.setFont("helvetica", "bolditalic");

... do some stuff ... Then I want 'normal' instead of bold italic

this.doc.setFontType('normal');

... which gives error:

"TypeError: this.doc.setFontType is not a function"
