+    This property allows requesting multisampled rendering in the layer.
+
+    By default multisampling is enabled whenever multisampling is
+    enabled for the entire window, assuming the scenegraph renderer in
+    use and the underlying graphics API supports this.
+
+    By setting the value to 2, 4, etc. multisampled rendering can be requested
+    for a part of the scene without enabling multisampling for the entire
+    scene. This way multisampling is applied only to a given subtree, which can
+    lead to significant performance gains since multisampling is not applied to
+    other parts of the scene.
+
+    \note Enabling multisampling can be potentially expensive regardless of the
+    layer's size, as it incurs a hardware and driver dependent performance and
+    memory cost.
+
+    \note This property is only functional when support for multisample
+    renderbuffers and framebuffer blits is available. Otherwise the value is
