Solaar is not using the symbolic versions of these icons because of a bug
external to Solaar that results in these icons not changing to the
foreground colour in the system tray. This can leave these icons nearly
invisible in dark themes.
invisible in dark themes. It would be useful to be able to switch to
symbolic icons via GTK styling (using something like
`.solaar * { -gtk-icon-style: symbolic; }` in the user's gtk.css)
but most or all current system tray implementations do not allow for this.
As a temporary hack setting the SOLAAR_TRAY_BATTERY_ICON_SYBOLIC environment
variable will cause Solaar to use symbolic icons for battery levels in the
system tray.
