+    Creates a new QSGTexture object from an existing native object.
+
+    The native object is wrapped, but not owned, by the resulting QSGTexture.
+    The caller of the function is responsible for deleting the returned
+    QSGTexture, but that will not destroy the underlying native object.
+
+    \a type specifies the type of the object. In practice the type is
+    NativeObjectTexture, indicating that the native object is a texture or
+    image of the underlying graphics API. Other types may be introduced in the
+    future.
+
+    This function is currently suitable for 2D RGBA textures only.
+
+    Unlike createTextureFromId(), this function supports both direct OpenGL
+    usage and the RHI abstracted rendering path.
+
+    \warning This function will return null if the scenegraph has not yet been
+    initialized.
+
+    Use \a options to customize the texture attributes. Only the
+    TextureHasAlphaChannel and TextureHasMipmaps are taken into account here.
+
+    \warning Unlike createTextureFromId(), this function never takes ownership
+    of the native object, and the TextureOwnsGLTexture flag is ignored.
+
+    \a size specifies the size in pixels.
+
+    \a nativeObjectPtr is a pointer to the native object handle. With OpenGL,
+    the native handle is a GLuint value, so \a nativeObjectPtr is then a
+    pointer to a GLuint. With Vulkan, the native handle is a VkImage, so \a
+    nativeObjectPtr is a pointer to a VkImage. With Direct3D 11 and Metal \a
+    nativeObjectPtr is a pointer to a ID3D11Texture2D or MTLTexture pointer.
+
+    \note Pay attention to the fact that \a nativeObjectPtr is always a pointer
+    to the native texture handle type, even if the native type itself is a
+    pointer.
+
+    \a nativeLayout is only used for APIs like Vulkan. When applicable, it must
+    specify the current image layout, such as, a VkImageLayout value.
