    textscreen: Set linear scaling for texture buffer.

    This is important for OS X - if multiple displays are connected, not
    all of them may be retina displays, so the window may be rendered as
    though it is always on a retina display. In this case, it's important
    to use linear scaling as the default nearest scaling can cause the
    large font to be distorted.
