Lazzexus 2ce31a1a30 Add image annotation / drawing mode 
Adds a draw mode toggle (pencil icon, shortcut D) that reveals a
bottom toolbar with freeform pen and shape tools (rectangle, ellipse,
triangle, star), a colour picker, line-width spinner, undo (Ctrl+Z),
clear-all, and a "Save Copy…" button that exports a flattened PNG.

Copying to clipboard (Ctrl+C) also flattens the annotations when any
strokes are present. Strokes are stored in image-pixel coordinates and
rendered via a Cairo overlay in the snapshot pipeline, so they remain
correctly positioned during zoom and pan.

Supported Image Formats

Image Viewer uses glycin for loading images. You can check glycin's README for more details about the formats supported by the default loaders. However, glycin supports adding loaders for additional formats. Therefore, the supported formats on your system may vary and might be changed by installing or removing glycin loaders.
