Struct Font 

pub struct Font(/* private fields */);

A font instance with runtime data

This represents a single font that can be used for text rendering. Fonts are managed by the FontAtlas and should not be created directly.

TODO: Currently using pointer wrapper approach for simplicity. Future improvement: Implement complete field mapping like imgui-rs for better type safety.

Note: Our dear-imgui-sys uses newer ImGui version with ImFontBaked architecture, while imgui-rs uses older version with direct field mapping. This difference requires careful consideration when implementing full mapping.

Implementations
