<function name="pango_font_face_describe">
<description>
Returns the family, style, variant, weight and stretch of
a #PangoFontFace. The size field of the resulting font description
will be unset.

<function name="pango_layout_get_tabs">
<description>
Get the current #PangoTabArray used by this layout. If no
#PangoTabArray has been set, then the default tabs are in use
and an invalid instance is returned. Default tabs are every 8 spaces.

</description>
<parameters>
<parameter name="layout">

<return> a copy of the tabs for this layout.

<function name="pango_context_get_metrics">
<description>
Get overall metric information for a font particular font
description.  Since the metrics may be substantially different for
different scripts, a language tag can be provided to indicate that
the metrics should be retrieved that correspond to the script(s)
used by that language.

The #PangoFontDescription is interpreted in the same way as
by pango_itemize(), and the family name may be a comma separated
list of figures. If characters from multiple of these families
would be used to render the string, then the returned fonts would
be a composite of the metrics for the fonts loaded for the
individual families.

<function name="pango_font_get_glyph_extents">
<description>
Gets the logical and ink extents of a glyph within a font. The
coordinate system for each rectangle has its origin at the
base line and horizontal origin of the character with increasing
coordinates extending to the right and down. The macros PANGO_ASCENT(),
PANGO_DESCENT(), PANGO_LBEARING(), and PANGO_RBEARING can be used to convert
from the extents rectangle to more traditional font metrics. The units
of the rectangles are in 1/PANGO_SCALE of a device unit.
