%description -n %lname
The idea of xBR is to scale bitmaps using pattern recognition (like
HQx), but also uses a 2-stage set of interpolation rules, which
better handle more complex patterns such as antialiased lines and
curves. Background textures keep the sharp characteristics of the
original image rather than becoming blurry like with HQx.

xBRZ follows this idea, but has a different set of rules, focusing on
preserving small image features consisting of few pixels only, like
commonly used in faces.
