1. A device comprising:
at least one computer memory that is not a transitory signal and that comprises instructions executable by at least one processor to:
identify at least one distortion function associated with at least one component of a display device;
adapt at least one flexible scale rasterization (FSR) function to the distortion function at least in part by:
moving at least a first control point of plural control points of the FSR function along the FSR function from an initial location of the first control point until a longest portion of the FSR function satisfying a value is identified;
moving additional control points of the FSR function from respective initial locations until respective longest portions of the FSR function satisfying a value are identified to render an adjusted FSR function; and
using the adjusted FSR function to present at least one image on the display device, wherein the FSR comprises a piecewise function having plural intervals each of which is a curve whose shape is defined by a size of the respective interval and an alpha value.
