How can I configure the tax format on the PDF invoice?

Following a sample for a AdvancedInvoiceLayout tax configuration that many of our German shop owners use (based on Magento 1.7.x):

• System » Configuration » AdvancedInvoiceLayout » General » Tax Display: Including Tax
• System » Configuration » Tax » Orders, Invoices, Credit Memos Display Settings » Include Tax In Grand Total: Yes
• System » Configuration » Tax » Orders, Invoices, Credit Memos Display Settings » Display Full Tax Summary: Yes
  (if this is set to "No" tax is not splitted into percent classes)
