v0.42.0

Breaking Changes

• Bumped glamx dependency: 0.2 → 0.3. (#384)

New Features

Off-screen Rendering (#382)

• Added OffscreenSurface: a truly headless render target with no window and no event loop — works on CI, servers and other environments without a display server (native only).
  • OffscreenSurface::new(width, height) / with_setup(width, height, CanvasSetup)
  • render_3d / render_2d / render — share the same scene graph, cameras, lights and materials as Window
  • render_image_3d — render a frame and capture it in one call
  • snap, snap_rect, snap_image, resize, size, width, height, set_background_color
• Hidden windows (Window::new_hidden*) now render into an off-screen texture, so snap* and the recording feature work on them too. (#381)
• Added the offscreen example.

Bug Fixes

• Fixed the first frame occasionally failing to render. A freshly created window — particularly on macOS — may need the event loop to be pumped a few times before its surface becomes presentable; surface acquisition now retries during a short startup grace period before giving up, then skips transient failures immediately on subsequent frames. (#381)
• Ensured the selected surface format is supported by the device features. (#379)
• Replaced stray println! / eprintln! calls in the rendering path and the OBJ/MTL loaders with log macros. (#381)
