(basic_engine_win32_new): this was a shape engine,
use correct type tag

* modules/basic/basic-ft2.c: delete the lang engine

* modules/arabic/arabic.c: Delete the lang engine
(arabic_engine_x_new): this is a shape
engine, not a lang engine, fix type tag

* pango/pango-layout.c (pango_layout_index_to_line_x): handle
the fact that paragraph delimiters aren't in the layout lines
(pango_layout_index_to_pos): update to handle paragraph
delimiters

* pango/break.c (pango_find_paragraph_boundary): New function
to find paragraph boundaries

 reflect the fact that paragraph separators are removed from the

 special-case start of line and whitespace-following-alphabetic

 Add directory for test programs, and a script to run them all
