I find a bug of "pango_layout_move_cursor_visually":
the layout text is "012345" , I move cursor from (index:100, trailing:100) to
left. I first get (5, 5). I think it should be (5, 1), that is the rightest
position.
the code is:
int index = 100;
int trailing
A few weeks ago I reported a performance issue regarding the use of
Uniscribe in the win32 basic shaper.
It turns out that the issue was with the use of Uniscribe's
SCRIPT_CACHE. Despite the name, this value is for caching
per-font-plus-size values, not per-script values. See:

Wow! Thank you very much for investigating. Will apply the patch
