Filtering - Bicubic, Hybrid, Hybrid+Bicubic etc.

[Papermanzero]

PPSSPP added 3 futher options beside xBRZ which are great for texture scaling.
Bicubic (sharper textures, but smoothed)
Hybrid (combination of linear and xBRZ)
Hybrid+Bicubic (which makes the transitions in the textures smooth)

It would be great if the tweak could add these filters, because of the gradiants within textures.
Bicubic makes the textures sharper then Bilinear. In combination with xBRZ the posterisation effect is also not so hard and visible.

Jinc2-Sharper scaler looks better than xBRZ in my opinion.
