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
