Admin 53e0e85b92 draw and widgets: Slug text everywhere, no blank glyphs, slimmer widgets 
All outline text draws with Slug curves on every platform (SDF/MSDF stays
selectable per size); a frame never presents a blank glyph and retained draw
lists keep theirs. One coverage model for vector feathering, widget families
split out of the core crate, fewer steady-state allocations, video keeps its
aspect (Contain/Cover), render and SSAO pass unification.
