M8: 50k-layer zoomed-out renders and faster save/load (#63)
Canvas previews zoomed out to 50% or less draw levels of detail (crates/render/src/lod.rs): subtrees under 2 device px are splatted as their averaged paint colours (box filter, no paths or effects), text under 4 px is greeked into bars, small solid rectangles are splatted and rectangular clip layers are composited without the blend pipeline. Image paints and masks keep the exact path. Exports, thumbnails and every other render stay exact (Options::lod is off by default); render bands are assembled with a row copy instead of a pixmap draw. .figcraft documents are serialized straight into the compressor and parsed straight from the text (a header pass reads version and image index without building a value tree); layer and text fields at their default values are left out (63 -> 22 MB of JSON at 50k layers, older files still load); JSON members use deflate level 3. At 50k layers: zoomed-to-fit render ~58 -> ~8 ms, save ~1.0 s -> ~0.09 s, load ~0.86 s -> ~0.16 s. Co-authored-by: Claude Opus 5.5 <noreply@anthropic.com>
