Thumbnail

Small RGBA buffer ready for ColorImage::from_rgba_unmultiplied.

Functions

load_thumbnail

Render a square-ish thumbnail no larger than max_dim per side. We reuse load_raw (which already caps at MAX_DISPLAY_DIM) and then decimate further by nearest-neighbour. This avoids dragging in any extra image-resize crate.
