Class Texture2DAtlas
A generic Atlas texture of 2D textures. An atlas texture is a texture collection that collects multiple sub-textures into a single big texture. Sub-texture allocation for Texture2DAtlas is static and will not change after initial allocation. Does not add mipmap padding for sub-textures.
