f51bed2a3b video-converter: don't convert too much 
because we do conversion after downscaling we only need to convert the
smallest width.

9396d843d6 video-blend: fix clipping of overlay images on the left 
Fix clipping of images that are partially left of the video
surface, they would get clipped on the right side instead of
the left side, because the video unpack functions currently
ignore the x offset parameter. Work around that until that
is implemented.

9032c12e69 video-blend: fix blending of rectangles partially or fully outside of the video 
In case of overlay being completely or partially outside
the video frame, the offset calculations are not right,
which resulted in the overlay not being displayed as
expected, or crashes due to invalid memory access.

When the overlay rectangle is completely outside,
we need not render the overlay at all.

For partial display of overlay rectangles, src_yoff
was not being calculated, hence it was always clipping
the bottom half of the overlay, By calculating the
src_yoff, now the overlay is clipped properly.
