It relies on external libraries for reading images in TIFF
and SVG formats. This option also adds such eye candy as
blending pixmap over root background, scaling and bluring of
-background pixmaps. Beware that with tis option enabled rxvt's
+background pixmaps. Beware that with this option enabled rxvt's
memory footprint will increase by anywhere between 750KBytes to 3 MB.
Memory footprint may somewhat be lowered if libAfterImage is
configured without support for SVG.
