+    When performing these calculations, it is assumed that all color
+    values are premultiplied with the corresponding alpha values (if
+    no alpha is specified, 1.0 is assumed). Then, the following
+    general compositing operation is performed:

+    different composite modes (wherein Aa and Ab denote source and
+    destination alpha, respectively).<p>
