Subject: [PATCH] vo_opengl: Super-xBR: add antiring and offset-bias suboptions

Add Hyllian's tweakable antiringing algorithm. superxbr-antiring
suboption can be between 0.0 and 1.0 (default=0). Add offset-bias
setting to tweak how Super-xBR is applied, setting this to lower values
can help with having thinner edges.
superxbr-offset-bias suboption can be between 0.01 and 1.0

    original hlsl by Christian Cann Schuldt Jensen ~ CeeJay.dk
    port to glsl by Anon

    It blurs the original pixel with the surrounding pixels and then subtracts this blur to sharpen the image.
    It does this in luma to avoid color artifacts and allows limiting the maximum sharpning to avoid or lessen halo artifacts.
