pango.analysis.Analysis for text
Byte offset of text from the beginning of the paragraph, or -1 to ignore attributes from analysis
array with one pango.types.LogAttr per character in text, plus one extra, to be filled in
Apply language-specific tailoring to the breaks in attrs.
The line breaks are assumed to have been produced by funcPango.default_break.
If offset is not -1, it is used to apply attributes from analysis that are relevant to line breaking.
Note that it is better to pass -1 for offset and use funcPango.attr_break to apply attributes to the whole paragraph.
