`PangoXftFont` is an implementation of `PangoFcFont` using the Xft
library for rendering. It is used in conjunction with `PangoXftFontMap`.
Returns the `XftFont` of a font.

a `PangoFont`
Returns the X display of the `XftFont` of a font.
the X display of the XftFont associated to @font.
a `PangoFont`
Gets the glyph index for a given Unicode character
for @font.
If you only want to determine whether the font has
the glyph, use pango_xft_font_has_char().
Use pango_fc_font_get_glyph() instead.
the glyph index, or 0, if the Unicode
character does not exist in the font.

Unicode codepoint to look up
Returns the index of a glyph suitable for drawing @wc as an
unknown character.
Use PANGO_GET_UNKNOWN_GLYPH() instead.
a glyph index into @font.
a `PangoFont`
the Unicode character for which a glyph is needed.
Determines whether @font has a glyph for the codepoint @wc.
Use pango_fc_font_has_char() instead.
%TRUE if @font has the requested codepoint.
a `PangoFont` for the Xft backend
Unicode codepoint to look up
Gets the FreeType `FT_Face` associated with a font.
This face will be kept around until you call pango_xft_font_unlock_face().
Use pango_fc_font_lock_face() instead.
the FreeType `FT_Face` associated with @font.
a `PangoFont`
Releases a font previously obtained with
pango_xft_font_lock_face().
Use pango_fc_font_unlock_face() instead.

`PangoXftFontMap` is an implementation of `PangoFcFontMap` suitable for
the Xft library as the renderer. It is used in to create fonts of
type `PangoXftFont`.
`PangoXftRenderer` is a subclass of `PangoRenderer` used for rendering
with Pango's Xft backend. It can be used directly, or it can be
further subclassed to modify exactly how drawing of individual
elements occurs.
Create a new `PangoXftRenderer` to allow rendering Pango objects
with the Xft library.
You must call pango_xft_renderer_set_draw() before
using the renderer.
the newly created `PangoXftRenderer`
an X display
the index of the screen for @display to which rendering will be done
Sets the default foreground color for a XftRenderer.
a XftRenderer

Sets the XftDraw object that the renderer is drawing to.
The renderer must not be currently active.

user data.
Retrieves a `PangoContext` appropriate for rendering with
Xft fonts on the given screen of the given display.
Use pango_xft_get_font_map() followed by
pango_font_map_create_context() instead.
the new `PangoContext`.
an X display.
an X screen.
Returns the `PangoXftFontMap` for the given display and screen.
The fontmap is owned by Pango and will be valid until
the display is closed.

an X display
the screen number of a screen within @display
Renders a `PangoGlyphString` onto an Xrender Picture object.
an X display
the source picture to draw the string with
the destination picture to draw the string onto
the font in which to draw the string
the glyph string to draw
the x position of start of string (in pixels)
the y position of baseline (in pixels)
Renders a `PangoGlyphString` onto an XftDraw object wrapping an X drawable.
the XftDraw object.
the color in which to draw the string
the font in which to draw the string
the glyph string to draw
the x position of start of string (in pixels)
the y position of baseline (in pixels)
Render a `PangoLayout` onto a XftDraw
an XftDraw
the foreground color in which to draw the layout
(may be overridden by color attributes)
a `PangoLayout`
the X position of the left of the layout (in Pango units)
the Y position of the top of the layout (in Pango units)
Render a `PangoLayoutLine` onto a XftDraw
an XftDraw
the foreground color in which to draw the layout line
(may be overridden by color attributes)
a `PangoLayoutLine`
the x position of start of string (in Pango units)
the y position of baseline (in Pango units)
Renders a `PangoGlyphString` onto a XftDraw, possibly
transforming the layed-out coordinates through a transformation
matrix.
Note that the transformation matrix for @font is not
changed, so to produce correct rendering results, the @font
must have been loaded using a `PangoContext` with an identical
transformation matrix to that passed in to this function.

units in user space coordinates)

in user space coordinates)
Sets a function that will be called to do final configuration
substitution on a #FcPattern before it is used to load
the font. This function can be used to do things like set
hinting and antialiasing options.
Use pango_fc_font_map_set_default_substitute()
instead.
an X Display

on #FcPattern objects.
data to pass to @func
function to call when @data is no longer used.
Release any resources that have been cached for the
combination of @display and @screen. Note that when the
X display is closed, resources are released automatically,
without needing to call this function.
an X display

Call this function any time the results of the
default substitution function set with
pango_xft_set_default_substitute() change.
That is, if your substitution function will return different
results for the same input pattern, you must call this function.
Use pango_fc_font_map_substitute_changed()
instead.
an X Display
the screen number of a screen within @display
