Adwaita-like SCTK Frame
Dark mode:
Title text: ab_glyph
By default title text is drawn with ab_glyph crate. This can be disabled by disabling default features.
Title text: crossfont
Alternatively title text may be drawn with crossfont crate. This adds a requirement on freetype.
sctk-adwaita = { default-features = false, features = ["crossfont"] }
