Re: Is pango_break suitable for breaking text into lines?

[Roman Beslik <rabeslik gmail com>]

Thank you for your anwser. I admit that I should calculate it myself, 
but I still do not know where can I get width of a cluster. BTW, what is 
a "cluster"? Pango manual does not have a glossary. Maybe I should get 
data from "pango_shape" and "PangoGlyphString" and "PangoGlyphInfo" and 
"PangoGlyphGeometry"? There are no glyph extents in 
"PangoGlyphGeometry", so I am stuck again.
