<description>
Finds the index of a feature.  If the feature is not found, sets
@feature_index to PANGO_OT_NO_FEATURE, which is safe to pass to
pango_ot_ruleset_add_feature() and similar functions.

In the future, this may set @feature_index to an special value that if used
in pango_ot_ruleset_add_feature() will ask Pango to synthesize the
requested feature based on Unicode properties and data.  However, this
function will still return %FALSE in those cases.  So, users may want to
ignore the return value of this function in certain cases.

<description>
Splits a shaped item (PangoGlyphItem) into multiple items based

affecting shaping, you filter them out (pango_attr_list_filter()),
apply the shaping process and then reapply them to the result using
this function.

All attributes that start or end inside a cluster are applied
to that cluster; for instance, if half of a cluster is underlined
and the other-half strikethrough, then the cluster will end
up with both underline and strikethrough attributes. In these
cases, it may happen that item-&amp;gt;extra_attrs for some of the
result items can have multiple attributes of the same type.

This function takes ownership of @glyph_item; it will be reused
as one of the elements in the list.

<function name="pango_cairo_font_map_new">
<description>
Creates a new #PangoCairoFontMap object; a fontmap is used
to cache information about available fonts, and holds
certain global parameters such as the resolution.
In most cases, you can use pango_cairo_font_map_get_default()
instead.

Note that the type of the returned object will depend
on the particular font backend Cairo was compiled to use;
You generally should only use the #PangoFontMap and
#PangoCairoFontMap interfaces on the returned object.

Gets the current run. When iterating by run, at the end of each

%NULL. The %NULL run at the end of each line ensures that all lines have
at least one run, even lines consisting of only a newline.

This is a faster alternative to pango_layout_iter_get_run(),
but the user is not expected
to modify the contents of the run (glyphs, glyph widths, etc.).

<description>
A monospace font is a font designed for text display where the the
characters form a regular grid. For Western languages this would
mean that the advance width of all characters are the same, but
this categorization also includes Asian fonts which include
double-width characters: characters that occupy two grid cells.
g_unichar_iswide() returns a result that indicates whether a
character is typically double-width in a monospace font.

The best way to find out the grid-cell size is to call
pango_font_metrics_get_approximate_digit_width(), since the results
of pango_font_metrics_get_approximate_char_width() may be affected
by double-width characters.

<function name="pango_script_get_sample_language">
<description>
Given a script, finds a language tag that is reasonably
representative of that script. This will usually be the
most widely spoken or used language written in that script:
for instance, the sample language for %PANGO_SCRIPT_CYRILLIC
is &amp;lt;literal&amp;gt;ru&amp;lt;/literal&amp;gt; (Russian), the sample language
for %PANGO_SCRIPT_ARABIC is &amp;lt;literal&amp;gt;ar&amp;lt;/literal&amp;gt;.

For some
scripts, no sample language will be returned because there
is no language that is sufficiently representative. The best
example of this is %PANGO_SCRIPT_HAN, where various different
variants of written Chinese, Japanese, and Korean all use
significantly different sets of Han characters and forms
of shared characters. No sample language can be provided
for many historical scripts as well.

As of 1.18, this function checks the environment variables
PANGO_LANGUAGE and LANGUAGE (checked in that order) first.
If one of them is set, it is parsed as a list of language tags
separated by colons or other separators.  This function
will return the first language in the parsed list that Pango
believes may use @script for writing.  This last predicate
is tested using pango_language_includes_script().  This can
be used to control Pango&apos;s font selection for non-primary
languages.  For example, a PANGO_LANGUAGE enviroment variable
set to &quot;en:fa&quot; makes Pango choose fonts suitable for Persian (fa) 
instead of Arabic (ar) when a segment of Arabic text is found
in an otherwise non-Arabic text.  The same trick can be used to
choose a default language for %PANGO_SCRIPT_HAN when setting
context language is not feasible.

<function name="pango_cairo_create_layout">
<description>
Creates a layout object set up to match the current transformation

used for text measurement with functions like
pango_layout_get_size() or drawing with functions like
pango_cairo_show_layout(). If you change the transformation
or target surface for @cr, you need to call pango_cairo_update_layout()

This function is the most convenient way to use Cairo with Pango,
however it is slightly inefficient since it creates a separate
#PangoContext object for each layout. This might matter in an
application that was laying out large amounts of text.

<function name="pango_ot_ruleset_new_for">
<description>
Creates a new #PangoOTRuleset for the given OpenType info, script, and
language.

This function is part of a convenience scheme that highly simplifies
using a #PangoOTRuleset to represent features for a specific pair of script
and language.  So one can use this function passing in the script and
language of interest, and later try to add features to the ruleset by just
specifying the feature name or tag, without having to deal with finding
script, language, or feature indices manually.

In excess to what pango_ot_ruleset_new() does, this function will:
&amp;lt;itemizedlist&amp;gt;
&amp;lt;listitem&amp;gt;
Find the #PangoOTTag script and language tags associated with
@script and @language using pango_ot_tag_from_script() and
pango_ot_tag_from_language(),
&amp;lt;/listitem&amp;gt;
&amp;lt;listitem&amp;gt;
For each of table types %PANGO_OT_TABLE_GSUB and %PANGO_OT_TABLE_GPOS,
find the script index of the script tag found and the language
system index of the language tag found in that script system, using
pango_ot_info_find_script() and pango_ot_info_find_language(),
&amp;lt;/listitem&amp;gt;
&amp;lt;listitem&amp;gt;
For found language-systems, if they have required feature
index, add that feature to the ruleset using
pango_ot_ruleset_add_feature(),
&amp;lt;/listitem&amp;gt;
&amp;lt;listitem&amp;gt;
Remember found script and language indices for both table types,
and use them in future pango_ot_ruleset_maybe_add_feature() and
pango_ot_ruleset_maybe_add_features().
&amp;lt;/listitem&amp;gt;
&amp;lt;/itemizedlist&amp;gt;

Because of the way return values of pango_ot_info_find_script() and
pango_ot_info_find_language() are ignored, this function automatically
finds and uses the &apos;DFLT&apos; script and the default language-system.

Return the Unix-style locale string for the language currently in

affect this through the environment variables LC_ALL, LC_CTYPE or
LANG (checked in that order). The locale strings typically is in
the form lang_COUNTRY, where lang is an ISO-639 language code, and
COUNTRY is an ISO-3166 country code. For instance, sv_FI for
Swedish as written in Finland or pt_BR for Portuguese as written in
Brazil.

On Windows, the C library doesn&apos;t use any such environment
variables, and setting them won&apos;t affect the behavior of functions
like ctime(). The user sets the locale through the Regional Options
in the Control Panel. The C library (in the setlocale() function)
does not use country and language codes, but country and language
names spelled out in English.
However, this function does check the above environment
variables, and does return a Unix-style locale string based on

First transforms @rect using @matrix, then calculates the bounding box

This function is useful for example when you want to draw a rotated
@PangoLayout to an image buffer, and want to know how large the image
should be and how much you should shift the layout when rendering.

If you have a rectangle in device units (pixels), use
pango_matrix_transform_pixel_rectangle().

If you have the rectangle in Pango units and want to convert to
transformed pixel bounding box, it is more accurate to transform it first
(using this function) and pass the result to pango_extents_to_pixels(),
as @ink_rect.  However, there is a reason that you may want to convert
to pixels first and then transform, and that is when the transformed
coordinates may overflow in Pango units (large matrix translation for
example).
