 * Picture Choices
 * Version 1.00
 * SumRndmDde
 *
 *
 * This is a plugin that allows players to have the ability to select from 
 * a collection of pictures.
 *
 *
 * ==========================================================================
 *  Where to Store the Pictures
 * ==========================================================================
 *
 * All of the image files need to be stored in:
 *
 *   /img/SumRndmDde/choices/
 *
 *
 * ==========================================================================
 *  How to Set up Picture Choices
 * ==========================================================================
 *
 * Within one of the slots for a Choice in a "Show Choices" event, use:
 *
 *   \picture[image-name]
 *
 * For example, if you had an image called "Happy.png", then you could do:
 *
 *   \picture[Happy]
 *
 *
 * Using this, you can assign pictures to each choice.
 * Keep in mind if even one choice is set up like this, the entire choice
 * window will use the Picture Choices format.
 * I would HIGHLY recommend making every choice have an picture assigned to it.
 *
 *
 * ==========================================================================
 *  Picture Choices Grid
 * ==========================================================================
 *
 * By default, the grid used for the Picture Choices is based on the amount
 * of choices that are used. 
 *
 * For example:
 *
 *   2 Choices   -   2 Columns | 1 Rows
 *   3 Choices   -   3 Columns | 1 Rows
 *   4 Choices   -   2 Columns | 2 Rows
 *   5 Choices   -   5 Columns | 1 Rows
 *   6 Choices   -   3 Columns | 2 Rows
 *
 *
 * However, say for example, you wish to set up a custom grid (like you may
 * wish to have 3 Rows for 3 Choices), you can use the Plugin Command:
 *
 *   SetPictureChoicesGrid [cols] [rows]
 *
 * For example:
 *
 *   SetPictureChoicesGrid 1 3
 *
 *
 * If you wish to set it back to automatic mode, use the Plugin Command:
 *
 *   SetPictureChoicesGrid auto
 *

 *
 *
 * Picture Choices
 * Version 1.00
 * SumRndmDde
 *
 *
 * プレイヤーが画像から選択できるようにするプラグインです。
 *
 * ==========================================================================
 *  画像の保存先
 * ==========================================================================
 *
 * 全ての画像ファイルを下記に保存する必要があります。
 *   /img/SumRndmDde/choices/
 *
 *
 * ==========================================================================
 *  画像選択の設定方法
 * ==========================================================================
 *
 * '選択肢の表示'イベントの選択肢のスロットのに、以下のように入力します。
 *
 *   \picture[image-name]
 *
 * 例えば、'Happy.png'という画像があったとします。
 *
 *   \picture[Happy]
 *
 *
 * これを使って、各選択肢に画像を割り当てることができます。
 * 1つの選択肢でもこのように設定されている場合、
 * 選択肢ウィンドウ全体が'Picture Choices'書式を使用します。
 * 全ての選択肢に画像を割り当てることを強くお勧めします。
 *
 *
 * ==========================================================================
 *  画像選択グリッド
 * ==========================================================================
 *
 * 下記//の行はヘルプの翻訳ですが、動作確認(コア1.6.2)では横一行に並びます。
 *
 * //  デフォルトでは、画像の選択肢に使用されるグリッドは、
 * //  使用される選択肢の量に基づいています。
 * //
 * //  例:
 * //
 * //    2つの選択肢   -   2 列 | 1 行
 * //    3つの選択肢   -   3 列 | 1 行
 * //    4つの選択肢   -   2 列 | 2 行
 * //    5つの選択肢   -   5 列 | 1 行
 * //    6つの選択肢   -   3 列 | 2 行
 *
 *
 * カスタムグリッドを設定したい場合(3つの選択肢に3つの行を設定したい場合等)、
 * プラグインコマンドを使用することができます。
 *
 *   SetPictureChoicesGrid [cols] [rows]
 *
 * 例:
 *
 *   SetPictureChoicesGrid 1 3
 *
 *
 * 自動モードに戻したい場合、プラグインコマンドを使用します。
 *
 *   SetPictureChoicesGrid auto
 *
