A new L4 crate that writes layers as an Android Vector Drawable (XML): shapes, booleans and text as baked path data, solid and gradient fills (linear, radial and sweep, exact for any handle frame via a group and a 2x2 SVD), native strokes where Android draws them the same and filled stroke outlines otherwise, clip frames and masks as <clip-path> groups. What a drawable can't hold is governed by Compat (bestEffort / exact / ignore): layer opacity over overlapping shapes, even-odd fills and clips (rewritten to non-zero via pathops), diamond gradients, alpha masks; effects, image and pattern fills and blend modes are left out with a warning. Output is pretty-printed, numbers are finite and short, names (android:name) are optional, escaped and unique.
