	48	<h2><center>Alpha Drawing</center></h2>
	49
	50	The wx.DC on Mac now supports alpha transparent drawing using pens and
	51	brushes. This is accomplished by enabling the wx.Colour class to have
	52	a fourth component for the alpha value, where 0 is fully transparent,
	53	and 255 is fully opaque.
	54
	55	<p>You can consider this a \"preview of coming attractions\" for the
	56	other platforms.
