#17 missing _width() function

[Ian]

The _write() function around line 130 of TTF.php refers to a $this->_height() function which doesn't appear to be there. I fixed this by adding in this function:

function _height($text, $angle = false) {
return $this->height($text, $angle);
}

Which made things work for me.

The error was appearing when I was trying to set the angle of some TTF text to 90.
