Detailed Description

2D texture resource and a path-keyed cache (TextureManager).

Loading a texture

Prefer TextureManager::GetOrLoadTexture() over Texture::Load() directly — the manager returns the same shared_ptr for repeated requests to the same path, avoiding redundant GPU uploads.

auto tex = Engine::GetInstance().GetTextureManager()
                   .GetOrLoadTexture("assets/textures/wall.png");
material->SetParam("uDiffuse", tex);

Textures are uploaded to the GPU in Texture::Init() using stb_image for decoding. The GL texture object is deleted in the destructor.
