b2r2: Improve image quality for HDMI clone
The downscale filter for scale factors from 1 to 1.4
has been modified to reduce ringing effects. Ringing
effects occur when the filter is a sinc function and the
input is the step function (high contrast, e.g. a black
line on a white surface). Destination pixels that were
close to high contrast edges could be visibly contaminated
by content from the opposite side of the edge.
