		1521	=head2 ALPHA CHANNEL SUPPORT
		1522
		1523	If Xft support has been compiled in and as long as Xft/Xrender/X don't get
		1524	their act together, rxvt-unicode will do it's own alpha channel management:
		1525
		1526	You can prefix any colour with an opaqueness percentage enclosed in
		1527	brackets, i.e. C<[percent]>, where C<percent> is a decimal percentage
		1528	(0-100) that specifies the opacity of the colour, where C<0> is completely
		1529	transparent and C<100> is completely opaque. For example, C<[50]red> is a
		1530	half-transparent red, while C<[95]#00ff00> is an almost opaque green. This
		1531	is the recommended format to specify transparency values, and works with
		1532	all ways to specify a colour.
		1533
		1534	For complete control, rxvt-unicode also supports
		1535	C<rgba:rrrr/gggg/bbbb/aaaa> (exactly four hex digits/component) colour
		1536	specifications, where the additional C<aaaa> component specifies opacity
		1537	(alpha) values. The minimum value of C<0000> is completely transparent,
		1538	while C<ffff> is completely opaque). The two example colours from
		1539	earlier could also be specified as C<rgba:ff00/0000/0000/8000> and
		1540	C<rgba:0000/ff00/0000/f332>.
		1541
		1542	You probably need to specify B<"-depth 32">, too, to force a visual with
		1543	alpha channels, and have the luck that your X-server uses ARGB pixel
		1544	layout, as X is far from just supporting ARGB visuals out of the box, and
		1545	rxvt-unicode just fudges around.
		1546
		1547	For example, the following selects an almost completely transparent black
		1548	background, and an almost opaque pink foreground:
		1549
		1550	@@RXVT_NAME@@ -depth 32 -bg rgba:0000/0000/0000/4444 -fg "[80]pink"
		1551
		1552	When not using a background image, then the interpretation of the
		1553	alpha channel is up to your compositing manager (most interpret it as
		1554	transparency of course).
		1555
		1556	When using a background pixmap or pseudo-transparency, then the background
		1557	colour will always behave as if it were completely transparent (so the
		1558	background image shows instead), regardless of how it was specified, while
		1559	other colours will either be transparent as specified (the background
		1560	image will show through) on servers supporting the RENDER extension, or
		1561	fully opaque on servers not supporting the RENDER EXTENSION.
		1562
		1563	Please note that due to bugs in Xft, specifying alpha values might result
		1564	in garbage being displayed when the X-server does not support the RENDER
		1565	extension.
