Does allsorts shape text in logical or visual order?

[LoganDark]

So in my prior discussion I asked for some more details on how to compose allsorts into a more complete layout engine. In there was some stuff like:

• Split text into runs of the same direction, script, font etc
• Shape each run individually then compose them later

My question is, does allsorts shape text in logical or visual order? If I'm shaping a run of Arabic text, do I need to have unicode-bidi reverse the codepoints before passing them to Font::shape, or is TextDirection::RightToLeft enough?

P.S. This is an issue because it should be documented

Had to double check this but confirming that shaping is done in logical order so there is no need to reverse the input text when using TextDirection::RightToLeft.

P.S. This is an issue because it should be documented

I'll keep it open until the docs have been updated.
