.linked assumes the container is a GtkBox, which is documented as never flipping children in RTL, so :first-child is always the left child, etc. GtkBox does that by reordering its CSS nodes when the direction changes. But most widgets don’t do that, so :first|last-child are 1st/last ADDED and swap sides in RTL. GtkPathBar is so, and ignoring that in our themes meant that in RTL, its left/right buttons got each other’s borders. Yuk! This patch adds the groundwork for supporting widgets like that, via the %linked_flippable placeholder, and applies that to override buttons in filechooser .path-bar.linked > button so that the correct borders get applied to those buttons when using RTL. Note that I select only PathBars within a FileChooser because we also have NautilusPathBar, which also uses widget.path-bar – but *does* flip its nodes for RTL already, so letting that get affected broke it again! https://bugzilla.gnome.org/show_bug.cgi?id=772817 |

Summary
-------
* Do not edit the CSS directly, edit the source SCSS files
* To be able to use the latest/adequate version of SASS, install sassc
* The configure script will detect whether or not you have sassc installed;
if you do, it will regenerate the CSS every time you modify the SCSS files
and rebuild GTK+.
How to tweak the theme
----------------------
Adwaita is a complex theme, so to keep it maintainable it's written and processed in SASS. The
generated CSS is then transformed into a GResource file during GTK+ build and used at runtime in a
non-legible or editable form.
It is very likely your change will happen in the _common.scss file. That's where all the widget
selectors are defined. Here's a rundown of the "supporting" stylesheets, that are unlikely to be the
right place for a drive by stylesheet fix:
_colors.scss - global color definitions. We keep the number of defined colors to a necessary minimum,
most colors are derived form a handful of basics. It covers both the light variant and
the dark variant.
_colors-public.scss - SCSS colors exported through gtk to allow for 3rd party apps color mixing.
_drawing.scss - drawing helper mixings/functions to allow easier definition of widget drawing under
specific context. This is why Adwaita isn't 15000 LOC.
_common.scss - actual definitions of style for each widget. This is where you are likely to add/remove
your changes.
You can read about SASS at http://sass-lang.com/documentation/. Once you make
your changes to the _common.scss file, GTK+ will rebuild the CSS files.
