+// Description:
+// The fix enables the fading effect with alpha-blending, which was not applied bofore.
+// The test will load a bitmap and two different masks: on/off and alpha-blend.
+// The bitmap will be masked with these masks and displayed before and after
+// setting the fading effect.
+// All different colour modes are being tested for both mask types.
+// The test will check the colour of a specific pixel in the scene before and after the
+// fading. The higher values in the After circle means that it has been highlighted.
+// The result will be printed in wstest log file.
+//
