* This type is used to fulfill textures for PromiseImages. Once an instance is returned from a
* PromiseImageTextureFulfillProc it must remain valid until the corresponding
* PromiseImageTextureReleaseProc is called. For performance reasons it is recommended that the
* the client reuse a single PromiseImageTexture every time a given texture is returned by
* the PromiseImageTextureFulfillProc rather than recreating PromiseImageTextures representing
* the same underlying backend API texture.
