It seems that you have investigate this quite deeply and I would love to commit and push your patch. However, I am a bit scared. Could somebody else who actually understands the issues involved have a look?

I wonder if this patch will then introduce significant rendering differences between platforms? Or do we have such anyway already (even if the same fonts are present)?

Lastly, can you confirm that your patch is licensed under LGPLv3+ and MPL1.1?
