Re: Printing with gtk+, cairo and pango - need to iterate glyphs and problems with pango attributes

[Behdad Esfahbod <behdad behdad org>]

1) pango_attr_size_new() takes size in pango units, so, replace:

pango_attr_size_new(14) with pango_attr_size_new(14*PANGO_SCALE)

2) pango_layout_get_size() and pango_glyph_string_extents() returns sizes in 
pango units, so instead of multiplying by PANGO_SCALE you should be dividing 
by PANGO_SCALE.

3) You set the string "0123456789" on the PangoLayout named "test_iterating", 
but iterate over the one named "layout".


I also suggest using PangoLayoutIter for iterating, and also use the baseline 
value instead of line hight for correct line positioning.
