GtkTextHandle was neglected by whoever removed the ::draw signal, leaving it entirely broken. Update to using GtkGizmo so we can implement snapshot of text handles. Input has received a revamp too, handling is done through a GtkGestureDrag and coordinate calculations simplified by storing the delta to the hotspot on ::begin instead of ::update, as this value is constant throughout the gesture. Widget state management on crossing events happens implicitly, so no longer needs to be done here. Last but not least, CSS has also been updated so handles are rendered at the correct size and proportion, and with the padding that code expects of it. |

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.
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.
