Enum Filter 

pub enum Filter {
    Nearest,
    Sharp,
    Xbr,
    Fsr,
    Crt,
}

How a 2D frame is scaled to the output.

Variants

Nearest

square pixels, nearest neighbour (linear when shrinking)

Sharp

integer prescale + bilinear: even pixels at any factor, exactly nearest at whole factors (the default)

Xbr

edge-directed (xBR level 2): rounds diagonals of pixel art

Fsr

AMD FSR 1 (EASU upscale + RCAS sharpen): rendered and dithered content

Crt

a CRT look: scanlines (a beam that widens with brightness) and an aperture grille

Implementations
