.SH DESCRIPTION
.ZN XmbDrawText
and 
.ZN XwcDrawText 
allow complex spacing and font set shifts between text strings.
Each text item is processed in turn, with the origin of a text
element advanced in the primary draw direction by the escapement of the
previous text item.
A text item delta specifies an additional escapement of the text item
drawing origin in the primary draw direction.
A font_set member other than 
.ZN None
in an item causes the font set to be used for this and subsequent text items
in the text_items list.
Leading text items with font_set member set to
.ZN None
will not be drawn.
.LP
.ZN XmbDrawText
and
.ZN XwcDrawText
do not perform any context-dependent rendering between text segments.
Clients may compute the drawing metrics by passing each text segment to
.ZN XmbTextExtents
and XwcTextExtents
or 
.ZN XmbTextPerCharExtents
and
.ZN XwcTextPerCharExtents .
When the 
.ZN XFontSet
has missing charsets, each unavailable character is drawn 
with the default string returned by 
.ZN XCreateFontSet .
The behavior for an invalid codepoint is undefined.
