Instead of hardcoding icon names in the widget, use arrow.none, arrow.up, arrow.down, arrow.left, arrow.right styles and set the icon to use with -gtk-icon-source. This lets themes change the icons that are used here, without forcing all uses of pan-up/down/start/end-symbolic to be treated the same. Document this in the menubutton CSS docs. |

Summary
-------
* To be able to use the latest/adequate version of sass, install sassc
* meson will regenerate the CSS every time you modify the SCSS files.
* Note that meson always builds out-of-tree, so the modified css files will
appear in your builddir.
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
from 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.
