Use Math.round instead of (int) to convert Key coordinates from float to int

        // Horizontal gap is divided equally to both sides of the key.

        mX = (int) (keyXPos + horizontalGap / 2);

        mX = Math.round(keyXPos + horizontalGap / 2);

        mY = keyYPos;

        mWidth = (int) (keyWidth - horizontalGap);

        mHorizontalGap = (int) horizontalGap;

        mHitBox.set((int)keyXPos, keyYPos, (int)(keyXPos + keyWidth) + 1, keyYPos + keyHeight);

        mWidth = Math.round(keyWidth - horizontalGap);

        mHorizontalGap = Math.round(horizontalGap);

        mHitBox.set(Math.round(keyXPos), keyYPos, Math.round(keyXPos + keyWidth) + 1,

                keyYPos + keyHeight);

        // Update row to have current x coordinate.

        row.setXPos(keyXPos + keyWidth);
