Blue outlines / focus rings
- introduce two new colors: $focus_border_color for focused / outlined elements and $_coloured_focus_border_color for focused / outlined elements with a colored background color, like suggested/destructive buttons or selected elements
- set outline / focus color, offset and style accordingly for all widgets
- adapt entry focus color
Similar to !1627 (closed) but adapted for gtk4 with
- :focus(visible) added to each widget
- without wildcards
- heavily increased the outline-offset for scales because the outline is drawn OVER the slider
😕 in gtk4, any other suggestion is welcome @jimmac
