Right now the sinus scroll is always 1 screen pixel, it should be 1 font pixel. If you scale the x of the font to 4, the scroll should be divided in 4 pixels chunks, not always 1. This will look more retro authentic and also use less CPU/GPU.
Actually it is splitted in font pixelsin x, but the sine value on y is in screen pixels. Which results in a smooth sine wave. So y should be in font pixels.
