Different spacing values for lines in pango layout

[Vitaly Ostanin <vyt vzljot ru>]

Hello.

Please, tell me, can I use different spacing values for lines in 
pango layout? I write custom tree model (in pygtk2) and custom 
cell renderer.

Cell renderer uses pango_layout for displaying multilined text in 
pygtk2 on_render (gtk_cell_renderer_render ()). Words in 
pango_layout requires different spacing above lines.

Such functionality exist in gtk_tree_view ():
I can set gtk_text_view_set_pixels_above_lines() for different 
tags. How can I use it for rendering custom cell renderer?
