IntPtr グラフィックス API に内在する深度バッファリソースを指すポインター
深度バッファリソースを指すネイティブ (グラフィックス API に内在する) のポインターを取得します。
Use this function to retrieve a pointer/handle corresponding to the depth buffer
part of the RenderTexture, as it is represented on the native graphics API level.
This can be used to enable depth buffer manipulation from native code plugins.
Use Texture.GetNativeTexturePtr to get a native pointer to the color buffer
of a render texture, and this function to get to the depth buffer part. For Depth and ShadowMap
render texture formats, the two functions return the same resource. The two functions will also return
the same resource if anti aliasing is enabled in the project's quality settings.
Note that calling this function when using multi-threaded rendering will synchronize with the rendering
thread (a slow operation), so best practice is to set up needed texture pointers only at initialization
time.
