		1562	=head2 ALPHA CHANNEL SUPPORT
		1563
		1564	If Xft support has been compiled in and as long as Xft/Xrender/X don't get
		1565	their act together, rxvt-unicode will do its own alpha channel management:
		1566
		1567	You can prefix any colour with an opaqueness percentage enclosed in
		1568	brackets, i.e. C<[percent]>, where C<percent> is a decimal percentage
		1569	(0-100) that specifies the opacity of the colour, where C<0> is completely
		1570	transparent and C<100> is completely opaque. For example, C<[50]red> is a
		1571	half-transparent red, while C<[95]#00ff00> is an almost opaque green. This
		1572	is the recommended format to specify transparency values, and works with
		1573	all ways to specify a colour.
		1574
		1575	For complete control, rxvt-unicode also supports
		1576	C<rgba:rrrr/gggg/bbbb/aaaa> (exactly four hex digits/component) colour
		1577	specifications, where the additional C<aaaa> component specifies opacity
		1578	(alpha) values. The minimum value of C<0000> is completely transparent,
		1579	while C<ffff> is completely opaque). The two example colours from
		1580	earlier could also be specified as C<rgba:ff00/0000/0000/8000> and
		1581	C<rgba:0000/ff00/0000/f332>.
		1582
		1583	You probably need to specify B<"-depth 32">, too, to force a visual with
		1584	alpha channels, and have the luck that your X-server uses ARGB pixel
		1585	layout, as X is far from just supporting ARGB visuals out of the box, and
		1586	rxvt-unicode just fudges around.
		1587
		1588	For example, the following selects an almost completely transparent black
		1589	background, and an almost opaque pink foreground:
		1590
		1591	@@RXVT_NAME@@ -depth 32 -bg rgba:0000/0000/0000/4444 -fg "[80]pink"
		1592
		1593	When not using a background image, then the interpretation of the
		1594	alpha channel is up to your compositing manager (most interpret it as
		1595	transparency of course).
		1596
		1597	When using a background pixmap or pseudo-transparency, then the background
		1598	colour will always behave as if it were completely transparent (so the
		1599	background image shows instead), regardless of how it was specified, while
		1600	other colours will either be transparent as specified (the background
		1601	image will show through) on servers supporting the RENDER extension, or
		1602	fully opaque on servers not supporting the RENDER EXTENSION.
		1603
		1604	Please note that due to bugs in Xft, specifying alpha values might result
		1605	in garbage being displayed when the X-server does not support the RENDER
		1606	extension.
