1. A method for adjusting pixel values within a frame to be displayed, comprising: receiving, with one or more processors, first pixel values for a first set of pixels corresponding to a first window and second pixel values for a second set of pixels corresponding to a second window, wherein the first window and the second window are to be displayed within a frame; receiving, with the one or more processors, coordinates and pixel adjustment values for one or more control points within the first window, wherein the coordinates comprise a location within the first window of the control point, and wherein the pixel adjustment value for the control point comprises a magnitude value; calculating, with the one or more processors, pixel adjustment values for a plurality of pixels in the first set of pixels based, at least in part, on the coordinates and the pixel adjustment values for the one or more control points; determining, with the one or more processors, adjusted first pixel values for the plurality of pixels by applying the calculated pixel adjustment values to the plurality of pixels; and displaying, with the one or more processors, the first window and the second window within the frame based, at least in part, on the adjusted first pixel values, wherein the first window and the second window are at least partially overlapping within the frame.
