DESCRIPTION
The XmbTextEscapement, XwcTextEscapement and
Xutf8TextEscapement functions return the escapement in pix-
els of the specified string as a value, using the fonts
loaded for the specified font set. The escapement is the
distance in pixels in the primary draw direction from the
drawing origin to the origin of the next character to be
drawn, assuming that the rendering of the next character is
not dependent on the supplied string.
Regardless of the character rendering order, the escapement
is always positive.
The function Xutf8TextEscapement is an XFree86 extension
introduced in XFree86 4.0.2. Its presence is indicated by
the macro X_HAVE_UTF8_STRING.
