dmg 4c80c5fc42 Added/fixed some Pango APIs
* Added pango_layout_get_direction
* Added pango_layout_get_line_spacing / pango_layout_set_line_spacing
* Added pango_layout_line_get_height
* Added return type to pango_itemize_with_base_dir
* Fixed pango_layout_line_get_x_ranges
* Fixed pango_layout_get_log_attrs / pango_layout_get_log_attrs_readonly (using only readonly version because we make copy anyway, added LogAttr bitfield reading properties)
