/**

* 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.
