Code review comment for lp:~widelands-dev/widelands/RTL-alignment-fix

I am not actually sure there is a place where this currently makes any difference visually.

Most text areas are used in automove mode and automatically change their position and size based on the text, so text alignment doesn't matter unless they are resized from the outside. In the cases where such resizing is done (e.g. window titles) the alignment is kCenter. So visially nothing has changed yet.

I made the fix mainly so that RTL would be displayed correctly when we use single-line textareas in non-center mode and with properly set layout. And we already do the same adjustment for multi-line textareas.

Where it theoretically could make a difference is the campaign select menu. That one uses some single-line textareas, but we don't have a layout defined there that would resize the text areas, so they stay collapsed to the text width and don't react to my fix yet. (And we might even put everything there in a multi-line textarea when we do a proper box layout.)

If you want to just quickly test it, set one of the menu title alignments to Left or Right. Without the fix, language doesn't make a diffence, with the fix alignment is swapped properly for Arabic.

Side note: Even the menus where we have defined a proper layout with multi-line textareas, some of them are not resized properly (like game/map name in the description area), so RTL is ignored.

I guess all this RTL stuff has very low priority anyway. Aside from a small amount of Arabic, we don't even seem to have translations.
