Fully tested it, and it's fixed. But try resizing the window and make it
half the width of Arabic text, and then largen it again: the bidi changes
when you largen it. BTW, that won't happen at the future when resizing
uses the visual buffer.

The main bug remains the non-spacing marks (including ZWNJ). They are
applied to the wrong buffer. For example, take a look at the attached
file that do not use any ZWNJ. The "besm.utf8" should come out like
"right.png", but comes out as "wrong.png".

Right to left natives expect the visual consistency.
