A right-to-left line draws the text before a tab after it, but its width was measured in the order of its text. A right-aligned line such as "אב גד<tab>הו זח" with a stop at 150 pt in a 300 pt frame ended 5.59 pt past the frame's right edge, and right, center and decimal stops aligned the text before the tab instead of the text drawn after it. - The line's width is measured in drawing order, each tab up to its stop from where the glyphs drawn before it end. Right, Auto and centered lines are aligned by that width. Stops are still measured from the left edge. - Right, center and decimal stops align the text drawn after the tab. - Area type breaks a line with a tab where it fits as drawn, and wraps a line that fits only in the order of its text. Once the line holds a tab, it reads on while the least it can be drawn at fits, then ends at the latest break that fits as drawn: up to 256 breaks are measured from the latest back, and earlier breaks without a hyphen are bisected. Hyphenation points are measured as drawn the same way, so the line hyphenates at a point that fits. - Only lines of horizontal paragraphs with right-to-left text keep a list of their break candidates. - A tab that ends a wrapped right-to-left line is drawn before the line at its own width instead of pushing the line to the right.
