@defvar line-spacing
When this permanently buffer-local variable is non-nil, if its value is
an integer, that many pixels of extra space are put below each line. If
the value is a floating point number, compute the spacing by multiplying
the value by the default frame line height.
Note that this variable and the frame parameter @code{line-spacing}
(described above) control different things. The frame parameter is
involved in setting the frame line height (@pxref{Creating Frames}),
while the buffer-local variable is for already-created frames.
For example, if the frame parameter is nil, a variable value of 1.0
``double-spaces'' the display because for every line of text, there is
an additional full line of space put below it. Likewise, a value of 2.0
``triple-spaces'' the display, and so forth. If, on the other hand, the
frame parameter is 10, a variable value of 10 would effectively put 20
pixels of space under the text.

@defvar blink-cursor-alist

form @code{(@var{on-state} . @var{off-state})}. Whenever the cursor
