We've been through this: you need to dynamically compute the pixel
coordinate to align-to, as function of the string width.

The display engine considers the line as a whole only when the entire
screen line has been laid out, i.e. we get to a newline or the X
coordinate is at the right edge of the window. Before that, there's
no information about the "line context".
