/**
 * A workshop in Québec: two taxes on every job, each on its own line, each
 * with its own registration number, and each totalled apart in the report.
 *
 * The job is the one the pricing spec prices, 900 before tax, so the
 * figures here follow from those: GST at 5% is 45.00 and QST at 9.975% is
 * 89.775, which the sheet must print as 89.78 and add to 1,034.78. With the
 * 10% discount the base is 810, GST 40.50, QST 80.7975 printed as 80.80,
 * and the total 931.30. The split is opt-in, so the last test turns it off
 * again and shows a new job is back to one tax line.
 *
 * Serial: the tax settings are the workshop's, and every job here is created
 * after they change.
