is calculated by multiplying the default frame line height by the
given value.
If the line-height property value is t, the minimum line height is
the height of the default frame font.
If the line-height property value is a cons (RATIO . FACE), the
minimum line height is calculated as RATIO * height of named FACE.
RATIO is int or float. If FACE is t, it specifies the current face.
If the line-spacing property value is an integer, the value is used as
additional space to put after the display line; this overrides the
default frame line-spacing and any buffer local value of the
line-spacing variable.
If the line-spacing property value is an positive integer, the value
is used as additional pixels to insert after the display line; this
overrides the default frame line-spacing and any buffer local value of
the line-spacing variable.
If the line-spacing property value is a float, the value is multiplied
by the current height of the display row to determine the additional
space to put after the display line.
If the value is a negative integer, the absolute value is used as the
total height of the line, i.e. a varying number of pixels are
inserted after each line to make each line exactly that many pixels high.
If the line-spacing property may be a float or cons, the line spacing
is calculated as specified above for the line-height property.
** The buffer local line-spacing variable may now have a float value,
which is used as a height relative to the default frame line height.

* buffer.c (syms_of_buffer) <line-spacing>: Allow float value.
* dispextern.h (struct it): Remove member use_default_face.
Add members override_ascent, override_descent, override_boff.
* xdisp.c (init_iterator): Handle line-spacing float value.
Initialize override_ascent member.
(append_space_for_newline): Reset override_ascent.
Remove use_default_face.
(calc_line_height_property): New function to calculate value of
line-height and line-spacing properties. Look at overlays, too.
Set override_ascent, override_descent, override_boff members when
using another face than the current face. Float values are now
relative to the frame default font, by default; accept a cons
of ratio and face name to specify value relative to a specific face.
(x_produce_glyphs): Use calc_line_height_property.
Use override_ascent etc. when set to handle different face heights.
A negative line-spacing property value is interpreted as a total
line height, rather than inter-line spacing.
(note_mouse_highlight): Allocate room for 40 overlays initially.
