<!-- ##### SECTION Short_Description ##### -->
Functions to run the rendering pipeline

<!-- ##### SECTION Long_Description ##### -->
<para>
The Pango rendering pipeline takes a string of
Unicode characters and converts it into glyphs.
The functions described in this section accomplish
various steps of this process.

<!-- ##### STRUCT PangoContext ##### -->
<para>
The #PangoContext structure stores global information
used to control the itemization process. 
</para>


<!-- ##### STRUCT PangoItem ##### -->
<para>
The #PangoItem structure stores information about
a segment of text. It contains the following fields:
</para>

@offset: the offset of the segment from the beginning of the
         string in bytes.
@length: the length of the segment in bytes.
@num_chars: the length of the segment in characters.
@analysis: the properties of the segment.

<!-- ##### STRUCT PangoAnalysis ##### -->
<para>
The #PangoAnalysis structure stores information about
the properties of a segment of text. It has the following
fields:
</para>

@shape_engine: the engine for doing rendering-system-dependent processing.
@lang_engine: the engine for doing rendering-system-independent processing.
@font: 
@level: the bidrectional level for this segment.

@backspace_deletes_character: If set, backspace deletes one character

                              field is only meaningful on grapheme
                              boundaries (where @is_cursor_position is
                              set).  In some languages, the full grapheme
                              (e.g.  letter + diacritics) is considered a
                              unit, while in others, each decomposed
                              character in the grapheme is a unit. In the
                              default implementation of #pango_break, this
                              bit is set on all grapheme boundaries except
                              those following Latin, Cyrillic or Greek base
                              characters.
