nCine::ImGuiDrawing class
#include <nCine/Graphics/ImGuiDrawing.h>

Handles ImGui drawing.

Bridges the ImGui debug overlay to the engine renderer. Owns the ImGui shader program, vertex and index buffers and the GPU textures backing the ImGui font and user atlases. Depending on the mode selected at construction, it either submits RenderCommand instances through the scene-graph RenderQueue or issues the OpenGL draw calls directly.
