gnome-shell-adaptived

Mojave introduces the concept of a dynamic desktop. Some of the things implemented here are health oriented.

Dyanmic Wallpapers that change with time of day
- Gnome does this /usr/share/backgrounds/gnome
System wide dark mode
- Gnome does this, however it is not implemented in many themes.
- Application support is improving with this as they use newer gtk libs
- I will need to look into the gtk architecture as I scale this up
Dark resources are masked using gamma levels from the current background
- This eleminates the issues of greys not ever looking uniform between gnome shell themes
- According to the patrickcoffey blog I can override .css elements for the shell using this. I could in theory fork most of the default shell theme for dark mode and use an extension to modify the grey.

This is an effort to create a content aware dark mode for gnome.

Research

Some notes on Gnome Shell themes here. Likely depreciated.
gnome-shell theme elements are now part of gtk-3.0./usr/share/themes/Aadwaita/gtk-3.0/gtk.css
Peek might be a good source on how to get the region under a screen area. They also explain that xwayland must be used in order for it to work on native wayland sessions at this moment.
See this line in Flameshot which imports a utility from the KDE framework.
Blur is is considered by Apple an integral characteristic in Dark mode design. I should look into the efficacy of the css blur property.

Button click states now lighten when active in dark mode
Group boxes are almost the same color however 'illuminate' their border-radius so as to introduce the depth needed in dark mode
Shadows are modified see shadows

9:54 Dark-Mode is Content Focused Application design uses light elements carefully so as not to distract focus from content.

Mail offers an option. It would be nice to add a background option to geary to or even have it pull gnome or gtk's css color setting.

Implemneting Desktop Tinting should be the majority of the work in this project.

Take sample of desktop portion that is behind the window (mutter/gtk)
Derive average color for that x/y area
Blend that average color with the dark-mode gray (css/js?)
This final gray is used as the window-background property (css)
Controls inherit some of this themeing because they do not use a full 100% opacity. This enables some of the tinted colors to leech into their blacks, grays, and whites. (gtk/css?)

2 Shadows, diffused-shadow and rim-shadow

Rim shadow in dark mode is slightly crisper and higher (z index and contast / blur radius)
Stroke is added to the inner rim of the rim-shadow so that the window has more definition above its shadows

Find how and where to get the background average color from (bonus: get from region under window)
- https://github.com/GNOME/mutter/blob/master/src/compositor/meta-background.c
Find how to store the background color as a css property of js variable so that I can mask it
Implement the mask for the background color
Implement hte mask to add the gnome-std dark gray to the masked color (bonus: dont hard-code gnome gray)
Apply this to gnome-shell.css that overrides the .css properties defining the gray (bonus: apply this to gtk2 and qt-widgets as well)
Package this as a gnome theme and/or extension
Look into further implementing this into the gnome-shell core for upstream
