#==============================================================================
# Sistema de galeria de imagens.
#==============================================================================
# Para ativar o script use o comando abaixo através de um evento usando o
# comando chamar script. (Call Script)
#
# picture_gallery
#
#==============================================================================
# Para disponibilizar as imagens na galeria você deverá usar o seguinte
# código através do comando chamar script.
#
# enable_picture(ID)
#
# EX   enable_picture(10)
#
# Para desativar a imagem use o código abaixo
#
# disable_picture(ID)
#
#==============================================================================
# Você deverá criar uma pasta com o nome "Gallery" onde as imagens deverão
# ser gravadas.
#
# Graphics/Gallery/
#
# A nomeação das imagens devem ser numéricas. (ID da imagem)
# 0.jpg    (Imagem não disponível.)
# 1.jpg
# 2.jpg
# 3.jpg
# ...
#
#==============================================================================
# ● Version History
#==============================================================================
# 2.1 - Changed it so that it has 6 Pictures per Page and not 9
#
# 2.0 - Compatibilidade com resoluções maiores que o padrão normal.
#     - Compatibilidade com imagens de qualquer resolução.
#     - Velocidade de movimento baseado no tamanho da imagem.
#     - Adições de novos comandos e configurações visando melhor
#       versatilidade.
