Enable fSharpenMipmappedTextures in Skia

This enables a Skia option to bias LOD selection for mipmapped
textures by 1/2 level. That sharpens any downscaled images,
and effectively switches to linear blending for scale factors
above 1/sqrt(2).

On the linked bug, this dramatically improves the quality of
the small avatar images from resetera.com (#63 - #71).

Other cases in the bug are not addressed, particularly the
framer.com issues from #49. (Those issues appear even without
GPU rasterization, so the cause may be outside Skia).
