*
• v 0.25 16/07/2007
  * - added {@link forbidden} to set an array of forbidden MIME types
  * - implemented support for simple wildcards in {@link allowed} and {@link forbidden}, such as image/*
  * - preset the file extension to the desired conversion format when converting an image
  * - added read and write support for BMP images
  * - added a flag {@link file_is_image} to determine if the file is a supported image type
  * - the class now provides some information about the image, before calling {@link process}(). Available are {@link image_src_x}, {@link image_src_y} and the newly introduced {@link image_src_bits}, {@link image_src_pixels} and {@link image_src_type}. Note that this will not work if open_basedir restrictions are in place
  * - improved logging; now provides useful system information
  * - added some more pre-processing checks for files that are images: {@link image_max_width}, {@link image_max_height}, {@link image_max_pixels}, {@link image_max_ratio}, {@link image_min_width}, {@link image_min_height}, {@link image_min_pixels} and {@link image_min_ratio}
  * - added {@link image_ratio_pixels} to resize an image to a number of pixels, keeping aspect ratio
  * - added {@link image_is_palette} and {@link image_is_transparent} and {@link image_transparent_color} for GIF images
  * - added {@link image_default_color} to define a fallback color for non alpha-transparent output formats, such as JPEG or BMP
  * - changed {@link image_background_color}, which now forces transparent areas to be painted
  * - improved reflections and color overlays so that it works with alpha transparent images
  * - {@link image_reflection_color} is now deprecated in favour of {@link image_default_color}
  * - transparent PNGs are now processed in true color, and fully preserving the alpha channel when doing merges
  * - transparent GIFs are now automatically detected. {@link preserve_transparency} is deprecated
  * - transparent true color images can be saved as GIF while retaining transparency, semi transparent areas being merged with {@link image_default_color}
  * - transparent true color images can be saved as JPG/BMP with the semi transparent areas being merged with {@link image_default_color}
  * - fixed conversion of images to true color
*
• v 0.24 25/05/2007
  * - added {@link image_background_color}, to set the default background color of an image
  * - added possibility of using replacement tokens in text labels

  * - fixed a small bug when using greyscale filter and associated filters
  * - added {@link image_ratio_fill} in order to fit an image within some dimensions and color the remaining space. Very similar to {@link image_ratio_crop}
  * - improved the recursive creation of directories
  * - the class now converts palette based images to true colors before doing graphic manipulations
*
• v 0.23 23/12/2006
  * - fixed a bug when processing more than once the same uploaded file. If there is an open_basedir restriction, the class now creates a temporary file for the first call to process(). This file will be used for subsequent processes, and will be deleted upon calling clean()
*
• v 0.22 16/12/2006
  * - added automatic creation of a temporary file if the upload directory is not within open_basedir
  * - fixed a bug which was preventing to work on a local file by overwriting it with its processed copy
  * - added MIME types video/x-ms-wmv and image/x-png and fixed PNG support for IE weird MIME types
  * - modified {@link image_ratio_crop} so it can accept one or more from string 'TBLR', determining which side of the image is kept while cropping
  * - added support for multiple lines in the text, using "\n" as a line break
  * - added {@link image_text_line_spacing} which allow to set the space between several lines of text
  * - added {@link image_text_alignment} which allow to set the alignment when text has several lines
  * - {@link image_text_font} can now be set to the path of a GDF font to load external fonts
  * - added {@link image_reflection_height} to create a reflection of the source image, which height is in pixels or percentage
  * - added {@link image_reflection_space} to set the space in pixels between the source image and the reflection
  * - added {@link image_reflection_color} to set the reflection background color
  * - added {@link image_reflection_opacity} to set the initial level of opacity of the reflection
*
• v 0.21 30/09/2006
  * - added {@link image_ratio_crop} which resizes within {@link image_x} and {@link image_y}, keeping ratio, but filling the space by cropping excedent of image
  * - added {@link mime_check}, which default is true, to set checks against {@link allowed} MIME list
  * - if MIME is empty, the class now triggers an error
  * - color #000000 is OK for {@link image_text_color}, and related text transparency bug fixed
  * - {@link gd_version}() now uses gd_info(), or else phpinfo()
  * - fixed path issue when the destination path has no trailing slash on Windows systems
  * - removed inline functions to be fully PHP5 compatible
*
• v 0.20 11/08/2006

  * - added {@link dir_auto_chmod} to automatically chmod the destination directory if not writeable.
  * - added {@link dir_chmod} to set the default chmod to use.
  * - added {@link image_crop} to crop images
  * - added {@link image_negative} to invert the colors on the image
  * - added {@link image_greyscale} to turn the image into greyscale
  * - added {@link image_threshold} to apply a threshold filter on the image
  * - added {@link image_bevel}, {@link image_bevel_color1} and {@link image_bevel_color2} to add a bevel border
  * - added {@link image_border} and {@link image_border_color} to add a single color border
  * - added {@link image_frame} and {@link image_frame_colors} to add a multicolored frame
*
• v 0.19 29/03/2006
  * - class is now compatible i18n (thanks Sylwester).
  * - the class can mow manipulate local files, not only uploaded files (instanciate the class with a local filename).
  * - {@link file_safe_name} has been improved a bit.
  * - added {@link image_brightness}, {@link image_contrast}, {@link image_tint_color}, {@link image_overlay_color} and {@link image_overlay_percent} to do color manipulation on the images.
