SetAspectRatio should constrain the content area consistently across platforms

研究方向
Start at Window::SetAspectRatio and trace the platform-specific implementations, especially Windows WM_SIZING and programmatic resize handling, alongside Linux geometry hints and macOS contentAspectRatio. Done means the Flutter content area, rather than the whole window including non-client decorations, maintains the requested aspect ratio consistently across platforms.
由索引模型根據 Issue 內容生成。
描述
Window::SetAspectRatio() behaves differently per platform:
- macOS constrains the content area (
contentAspectRatio), unless the content is full-size. - Windows constrains the whole window rect in
WM_SIZING, title bar and borders included, so the Flutter view ends up with a different ratio. - Linux uses geometry hints on the window, and users report the content not matching the ratio.
Expected: the ratio applies to the content area on all platforms. On Windows, subtract the non-client size before applying the ratio in WM_SIZING, and apply it to programmatic resizes too.
Background:
- leanflutter/window_manager#437: exclude the title bar from the aspect-ratio calculation
- leanflutter/window_manager#520: actual window ratio differs from the one set
- leanflutter/window_manager#566: setAspectRatio behaves differently on Windows and Linux
