System Information
Operating system: GNU/Linux Ubuntu 19.04

Blender Version
Broken: 2.82
Worked: 2.79

Short description of error
When generating a rig with Rigify, if the metarig has any transform, the rig will be offset. The bones are copied in place but the object is created at the origin.

In this screenshot, the Root bone is the only one created at the origin, the other bones are on the metarig.

Exact steps for others to reproduce the error

Add metarig
Move it
Generate

One possible solution might be to give the metarig’s transforms to the rig:

diff --git a/rigify/generate.py b/rigify/generate.py
