+// we are always working with a 32 bit deep pixel buffer
+// under QuickDraw its alpha parts are going to be ignored in the GWorld,
+// therefore we have a separate GWorld there for blitting the mask in
+
+// under Quartz then content is transformed into a CGImageRef representing the same data
+// which can be transferred to the GPU by the OS for fast rendering
+
