/**
* Class upload
*
* <b>What does it do?</b>
*
* It manages file uploads for you. In short, it manages the uploaded file,
* and allows you to do whatever you want with the file, especially if it
* is an image, and as many times as you want.
*
* It is the ideal class to quickly integrate file upload in your site.
* If the file is an image, you can convert, resize, crop it in many ways.
* You can also apply filters, add borders, text, watermarks, etc...
* That's all you need for a gallery script for instance.
*
* You can also use the class to work on local files, which is especially
* useful to use the image manipulation features
*
* <b>How does it work?</b>
*
* You instanciate the class with the $_FILES['my_field'] array
* where my_field is the field name from your upload form.
* The class will check if the original file has been uploaded
* to its temporary location (alternatively, you can instanciate
* the class with a local filename).
*
* You can then set a number of processing variables to act on the file.
* For instance, you can rename the file, and if it is an image,
* convert and resize it in many ways.
* You can also set what will the class do if the file already exists.
*
* Then you call the function {@link process} to actually perform the actions
* according to the processing parameters you set above.
* It will create new instances of the original file,
* so the original file remains the same between each process.
* The file will be manipulated, and copied to the given location.
* The processing variables will be reseted once it is done.
*
* You can repeat setting up a new set of processing variables,
* and calling {@link process} again as many times as you want.
* When you have finished, you can call {@link clean} to delete
* the original uploaded file.
*
* If you don't set any processing parameters and call {@link process}
* just after instanciating the class. The uploaded file will be simply
* copied to the given location without any alteration or checks.
*
* Don't forget to add <i>enctype="multipart/form-data"</i> in your form
* tag <form> if you want your form to upload the file.
*
* <b>How to use it?</b><br>
* Create a simple HTML file, with a form such as:
* <pre>
* <form enctype="multipart/form-data" method="post" action="upload.php">
* <input type="file" size="32" name="image_field" value="">
* <input type="submit" name="Submit" value="upload">
* </form>
* </pre>
* Create a file called upload.php:
* <pre>
* $handle = new upload($_FILES['image_field']);
* if ($handle->uploaded) {
* $handle->file_new_name_body = 'image_resized';
* $handle->image_resize = true;
* $handle->image_x = 100;
* $handle->image_ratio_y = true;
* $handle->process('/home/user/files/');
* if ($handle->processed) {
* echo 'image resized';
* $handle->clean();
* } else {
* echo 'error : ' . $handle->error;
* }
* }

*
* <b>Changelog</b>
* <ul>
* <li><b>v 0.23</b> 23/12/2006<br>

* - added automatic creation of a temporary file if the upload directory is not within open_basedir<br>
* - fixed a bug which was preventing to work on a local file by overwriting it with its processed copy<br>
* - added MIME types video/x-ms-wmv and image/x-png and fixed PNG support for IE weird MIME types<br>
* - 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<br>
* - added support for multiple lines in the text, using "\n" as a line break<br>
* - added {@link image_text_line_spacing} which allow to set the space between several lines of text<br>

* - added {@link image_reflection_height} to create a reflection of the source image, which height is in pixels or percentage<br>
* - added {@link image_reflection_space} to set the space in pixels between the source image and the reflection<br>
* - added {@link image_reflection_color} to set the reflection background color<br>
* - added {@link image_reflection_opacity} to set the initial level of opacity of the reflection</li>
* <li><b>v 0.21</b> 30/09/2006<br>

* - added {@link mime_check}, which default is true, to set checks against {@link allowed} MIME list<br>
* - if MIME is empty, the class now triggers an error<br>
* - color #000000 is OK for {@link image_text_color}, and related text transparency bug fixed<br>

* - added {@link image_frame} and {@link image_frame_colors} to add a multicolored frame</li>
* <li><b>v 0.19</b> 29/03/2006<br>
* - class is now compatible i18n (thanks Sylwester).<br>

* - added security check on the file with a list of mime-types.<br>
* - changed the license to GPL v2 only</li>

* - added some more error reporting to avoid crash if GD is not present</li>
* <li><b>v 0.15</b> 16/04/2005<br>
* - added JPEG compression quality setting. Thanks Vad</li>
* <li><b>v 0.14</b> 14/03/2005<br>
