Detailed Description

ImGui/OpenGL/GLFW integration utilities and file dialog wrapper.

This header provides:

• Stream operator overload for ImGuiStyle debugging/printing
• FileDialog wrapper around Native File Dialog (NFD) for open/save/folder selection

The FileDialog class simplifies cross-platform file operations and integrates with std::filesystem for type-safe path handling.

Note

Relies on ImGui, GLFW, OpenGL, and Native File Dialog (NFD).

Warning

NFD allocations must be freed properly (handled internally here).
