In SWT, when the advanced graphics system is turn off ( GC#setAdvanced( false) ), the alpha is reset to its initial value 255.
Test case:
  public void testResetAlphaAfterUsingSetAdvanced() {
    Display display = new Display();
    GC gc = new GC( display, SWT.NONE );
    gc.setAlpha( 64 );    
    assertEquals( 64, gc.getAlpha() );
    assertTrue( gc.getAdvanced() );
    gc.setAdvanced( false );
    assertEquals( 255, gc.getAlpha() );
  }
