Chris@76: /*	This is perhaps the most important and probably most accessed files in all
Chris@76: 	of SMF.  This file controls topic, message, and attachment display.  It
Chris@76: 	does so with the following functions:
Chris@76: 
Chris@76: 	void Display()
Chris@76: 		- loads the posts in a topic up so they can be displayed.
Chris@76: 		- supports wireless, using wap/wap2/imode and the Wireless templates.
Chris@76: 		- uses the main sub template of the Display template.
Chris@76: 		- requires a topic, and can go to the previous or next topic from it.
Chris@76: 		- jumps to the correct post depending on a number/time/IS_MSG passed.
Chris@76: 		- depends on the messages_per_page, defaultMaxMessages and enableAllMessages settings.
Chris@76: 		- is accessed by ?topic=id_topic.START.
Chris@76: 
Chris@76: 	array prepareDisplayContext(bool reset = false)
Chris@76: 		- actually gets and prepares the message context.
Chris@76: 		- starts over from the beginning if reset is set to true, which is
Chris@76: 		  useful for showing an index before or after the posts.
Chris@76: 
Chris@76: 	void Download()
Chris@76: 		- downloads an attachment or avatar, and increments the downloads.
Chris@76: 		- requires the view_attachments permission. (not for avatars!)
Chris@76: 		- disables the session parser, and clears any previous output.
Chris@76: 		- depends on the attachmentUploadDir setting being correct.
Chris@76: 		- is accessed via the query string ?action=dlattach.
Chris@76: 		- views to attachments and avatars do not increase hits and are not
Chris@76: 		  logged in the "Who's Online" log.
Chris@76: 
Chris@76: 	array loadAttachmentContext(int id_msg)
Chris@76: 		- loads an attachment's contextual data including, most importantly,
Chris@76: 		  its size if it is an image.
Chris@76: 		- expects the $attachments array to have been filled with the proper
Chris@76: 		  attachment data, as Display() does.
Chris@76: 		- requires the view_attachments permission to calculate image size.
Chris@76: 		- attempts to keep the "aspect ratio" of the posted image in line,
Chris@76: 		  even if it has to be resized by the max_image_width and
Chris@76: 		  max_image_height settings.
Chris@76: 
Chris@76: 	int approved_attach_sort(array a, array b)
Chris@76: 		- a sort function for putting unapproved attachments first.
Chris@76: 
Chris@76: 	void QuickInTopicModeration()
Chris@76: 		- in-topic quick moderation.
