  *) Perkenalan :
  -----------------------------------------------------------------------------
  Script ini ngebikin kamu bisa nampilin animated portrait waktu dalam dialog.
  
  -----------------------------------------------------------------------------
  *) Cara penggunaan :
  -----------------------------------------------------------------------------
  Pasang script ini dibawah material namun diatas main
  
  Siapkan dua buah gambar ukuran terserah. Satu gambar untuk animasi idle. 
  Satu lainnya untuk animasi bicara. Gambar terdiri dari 3 grid kesamping. Beri
  nama dua gambar tersebut seperti ini
  
  namagambar_idle.png  << nama gambar untuk idle
  namagambar_talk.png  << nama gambar untuk bicara
  
  -----------------------------------------------------------------------------
  *) Script call:
  -----------------------------------------------------------------------------
  Untuk nampilin gambar dan semacemnya, gunakan script call sebagai berikut
  
  - set_portrait(filename, pos, flip, active)
    Script call ini untuk mengeset portrait. Keterangannya kek gini
    
    *) Filename >> adalah nama file gambar yang ditulis dalam kutip (""). 
       Kamu tidak perlu menambahkan _talk / _idle dalam pemanggilannya.
    *) Pos >> untuk posisi. Pilih antara A (kiri), B (kanan), dan C (tengah)
    *) Flip >> apakah gambarnya dibalik atau tidak. Cukup tuliskan true
       atau false (bisa diabaikan. Default : false)
    *) Active >> Apakah gambar tersebut aktif? Jika true, maka saat text
       berjalan, gambar tersebut akan berbicara. (Default : true)
       
  - remove_portrait(pos)
    Untuk menghilangkan salah satu portrait. Pos isi dengan A atau B
  
  - active_portrait(pos)
    Untuk mengganti portrait mana yang aktif
    
  - clear_portrait
    Untuk menghilangkan portrait yang ada
    
  - $game_system.portrait_ypos[pos] = value
    Untuk mereposisi tempat portrait di tampilkan. Ganti pos dengan 
    (:A, :B, :C). Ganti value dengan angka. Contoh :
    
    $game_system.portrait_ypos[:B] = 60

    Talk_Refresh_Rate = 4 
  # Refresh rate gambar yang sedang aktif. Jika kamu memasukkan angka 4, maka

    Idle_Interval = [20,120]
  # Interval atau selang animasi idle. Format [absolute wait, random wait]
  #
  # *) absolute wait  >> Selang tunggu absolut dalam hitungan frame
  # *) random wait    >> Selang tunggu acak
  #
  # Jika kamu mengisinya [20, 120] maka itu artinya, jeda antara animasi idle
  # satu dengan yang adalah 20 ditambah angka acak dari 0 - 120. 
  # (default : [20,120])
  #
  # Note : 60 frame adalah 1 detik
