Arguments: stream
Returns the line height of the argument stream.
stream should be a graphical-stream
.
The line height is the number of pixels taken up by a line of text, from the baseline of one line to the baseline of the next. When a newline is printed to the stream (as with draw-string-in-box or format), the current-position-y of the stream is incremented by this amount (and the current-position-x is set to the stream's left-margin).
The line-height is set automatically to equal the font-height of the initial font of the stream, and when (setf font) or with-font is called on the stream. It may also be set directly if needed by calling (setf line-height).
