    Would overlap work for you ?

    Each leds screen co ordinated can be overlapped so an area on the screen will partially light multiple leds

    Yeah the Overlap feature seems to do spatial anti-aliasing! I think this is the function that does it:

    which returns the average color of a range of pixels.

    Video libraries like FFmpeg/libav/gstreamer implement more 'scaling algorithms' (e.g. link). But I think they would add a lot of computational expense, even if they use hardware acceleration, so they might not be much of an enhancement.
