- CGraphicFontTexture rasterises glyph pages at the swapchain density (UISetFontOversample, MT_FONT_OVERSAMPLE) with anti-aliased coverage; metrics, packing and UVs stay the 40250 1x values. Default 1 keeps the verbatim bilevel path (Godot unchanged). - native.frag: sharp-bilinear sampling for magnified UI textures. - Multisampled colour/depth with a resolve into the swapchain (MT_MSAA, default 4); stats line reports msaa=N.
