		1563	=head2 ALPHA CHANNEL SUPPORT
		1564
		1565	If Xft support has been compiled in and as long as Xft/Xrender/X don't get
		1566	their act together, rxvt-unicode will do its own alpha channel management:
		1567
		1568	You can prefix any colour with an opaqueness percentage enclosed in
		1569	brackets, i.e. C<[percent]>, where C<percent> is a decimal percentage
		1570	(0-100) that specifies the opacity of the colour, where C<0> is completely
		1571	transparent and C<100> is completely opaque. For example, C<[50]red> is a
		1572	half-transparent red, while C<[95]#00ff00> is an almost opaque green. This
		1573	is the recommended format to specify transparency values, and works with
		1574	all ways to specify a colour.
		1575
		1576	For complete control, rxvt-unicode also supports
		1577	C<rgba:rrrr/gggg/bbbb/aaaa> (exactly four hex digits/component) colour
		1578	specifications, where the additional C<aaaa> component specifies opacity
		1579	(alpha) values. The minimum value of C<0000> is completely transparent,
		1580	while C<ffff> is completely opaque). The two example colours from
		1581	earlier could also be specified as C<rgba:ff00/0000/0000/8000> and
		1582	C<rgba:0000/ff00/0000/f332>.
		1583
		1584	You probably need to specify B<"-depth 32">, too, to force a visual with
		1585	alpha channels, and have the luck that your X-server uses ARGB pixel
		1586	layout, as X is far from just supporting ARGB visuals out of the box, and
		1587	rxvt-unicode just fudges around.
		1588
		1589	For example, the following selects an almost completely transparent black
		1590	background, and an almost opaque pink foreground:
		1591
		1592	@@RXVT_NAME@@ -depth 32 -bg rgba:0000/0000/0000/4444 -fg "[80]pink"
		1593
		1594	When not using a background image, then the interpretation of the
		1595	alpha channel is up to your compositing manager (most interpret it as
		1596	transparency of course).
		1597
		1598	When using a background pixmap or pseudo-transparency, then the background
		1599	colour will always behave as if it were completely transparent (so the
		1600	background image shows instead), regardless of how it was specified, while
		1601	other colours will either be transparent as specified (the background
		1602	image will show through) on servers supporting the RENDER extension, or
		1603	fully opaque on servers not supporting the RENDER EXTENSION.
		1604
		1605	Please note that due to bugs in Xft, specifying alpha values might result
		1606	in garbage being displayed when the X-server does not support the RENDER
		1607	extension.
