pub const ICON_OVERSAMPLE: u32 = 2;Expand description
How much larger than the target (layout) size icons are rasterized, so Skia’s downscale keeps edges crisp under sub-pixel positioning and minor scale animations.
This lives here — not as a local const inside the painter — because it
must feed the exact same computation icon_cache_key uses. See that
function’s doc for why (issue #166).
