8.31: Convert from Board Coordinates to Pixel Coordinates

def convertToPixelCoords(boxx, boxy):
    # Convert the given xy coordinates of the board to xy
    # coordinates of the location on the screen.
    return (XMARGIN + (boxx * BOXSIZE)), (TOPMARGIN + (boxy * BOXSIZE))

This helper function converts the board’s box coordinates to pixel coordinates. This function works the same way to the other "convert coordinates" functions used in the previous game programs.
