Struct LayoutCallbackInfo 

pub struct LayoutCallbackInfo {
    pub window_size: WindowSize,
    pub theme: WindowTheme,
    pub gl_context: *const OptionGlContextPtr,
    /* private fields */
}

Gives the layout() function access to the RendererResources and the Window (for querying images and fonts, as well as width / height)

Fields

window_size: WindowSize

Window size (so that apps can return a different UI depending on the window size - mobile / desktop view). Should be later removed in favor of “resize” handlers and @media queries.

theme: WindowTheme

Registers whether the UI is dependent on the window theme

gl_context: *const OptionGlContextPtr

OpenGL context so that the layout() function can render textures
