SVG get text element width
...average of any valid results of the three methods. You could improve it to cast out outliers or to favor getComputedTextLength if the element is a text element.

putchar(*--y);

Now we have lots of casting, passing arguments to (recursive) main that are completely ignored (but evaluation to get the increment and decrement are utterly crucial), and of course that completely arbitrary looking number to cover up the fact t...
