1465(0-100) that specifies the opacity of the color, where C<0> is completely
1466transparent and C<100> is completely opaque. For example, C<[50]red> is a
1467half-transparent red, while C<[95]#00ff00> is an almost opaque green. This
1468is the recommended format to specify transparency values, and works with
1469all ways to specify a colour.

1493When using a background pixmap or pseudo-transparency, then the background
1494colour will always behave as if it were completely transparent (so the
1495background image shows instead), regardless of how it was specified, while
1496other colours will either be transparent as specified (the background
1497image will show through) on servers supporting the RENDER extension, or
1498fully opaque on servers not supporting the RENDER EXTENSION.

1500Please note that due to bugs in Xft, specifying alpha values might result
1501in garbage being displayed when the X-server does not support the RENDER
