The renderer function called after ImGui::Render() will receive that same value that the user code passed:
```cpp
// Cast ImTextureID / void* stored in the draw command as our texture type
MyTexture* texture = (MyTexture*)pcmd->TextureId;
MyTexture* texture = (MyTexture*)pcmd->GetTexID();
MyEngineBindTexture2D(texture);
```
Once you understand this design you will understand that loading image files and turning them into displayable textures is not within the scope of Dear ImGui.
