		1538	=head2 ALPHA CHANNEL SUPPORT
		1539
		1540	If Xft support has been compiled in and as long as Xft/Xrender/X don't get
		1541	their act together, rxvt-unicode will do its own alpha channel management:
		1542
		1543	You can prefix any colour with an opaqueness percentage enclosed in
		1544	brackets, i.e. C<[percent]>, where C<percent> is a decimal percentage
		1545	(0-100) that specifies the opacity of the colour, where C<0> is completely
		1546	transparent and C<100> is completely opaque. For example, C<[50]red> is a
		1547	half-transparent red, while C<[95]#00ff00> is an almost opaque green. This
		1548	is the recommended format to specify transparency values, and works with
		1549	all ways to specify a colour.
		1550
		1551	For complete control, rxvt-unicode also supports
		1552	C<rgba:rrrr/gggg/bbbb/aaaa> (exactly four hex digits/component) colour
		1553	specifications, where the additional C<aaaa> component specifies opacity
		1554	(alpha) values. The minimum value of C<0000> is completely transparent,
		1555	while C<ffff> is completely opaque). The two example colours from
		1556	earlier could also be specified as C<rgba:ff00/0000/0000/8000> and
		1557	C<rgba:0000/ff00/0000/f332>.
		1558
		1559	You probably need to specify B<"-depth 32">, too, to force a visual with
		1560	alpha channels, and have the luck that your X-server uses ARGB pixel
		1561	layout, as X is far from just supporting ARGB visuals out of the box, and
		1562	rxvt-unicode just fudges around.
		1563
		1564	For example, the following selects an almost completely transparent black
		1565	background, and an almost opaque pink foreground:
		1566
		1567	@@RXVT_NAME@@ -depth 32 -bg rgba:0000/0000/0000/4444 -fg "[80]pink"
		1568
		1569	When not using a background image, then the interpretation of the
		1570	alpha channel is up to your compositing manager (most interpret it as
		1571	transparency of course).
		1572
		1573	When using a background pixmap or pseudo-transparency, then the background
		1574	colour will always behave as if it were completely transparent (so the
		1575	background image shows instead), regardless of how it was specified, while
		1576	other colours will either be transparent as specified (the background
		1577	image will show through) on servers supporting the RENDER extension, or
		1578	fully opaque on servers not supporting the RENDER EXTENSION.
		1579
		1580	Please note that due to bugs in Xft, specifying alpha values might result
		1581	in garbage being displayed when the X-server does not support the RENDER
		1582	extension.
