Description

Could you please implement xBR shader or xBRZ filter or both in Dolphin. It would be very beneficial for 2D and sprite-based games.
xBR and xBRZ are pixel art scaling algorithms ,they give best results in 2D/sprite based games with low resolution textures and games with pre-rendered backgrounds which dont upscale well with higher internal resolutions. XBR/XBRZ is used with good results in emulators like Retroarch,Higan,Desmume and for example PPSSPP can use both XBRZ and increase internal resolution.

Here is explanation:http://code.google.com/p/2dimagefilter/wiki/ImageScaling#xBR

Here is comparison for 3D graphics:http://blog.metaclassofnil.com/?p=306
