* Added support for configuration of an arbitrary number of commons-style file repositories.
* Split Image.php into filerepo/File.php and filerepo/LocalFile.php
* Renamed Image::getImagePath() to File::getPath()
* Added initial support for timestamp-based file fetching (OldLocalFile), to be expanded upon by aaron.
* Changed the interface for Image/File object creation: use wfFindFile() or wfLocalFile() depending on semantics
* ImageGallery::add() now accepts a title object as the first parameter
* Moved file handling operations on upload from SpecialUpload to File
* Removed path-related functions from ImageFunctions.php. Removed static path accessors from File.
* Added a Content-Disposition header to thumb.php output
* Improved thumb.php error handling
* Updated the unit test suite to kind of partially work with modern computers. RunTests.php doesn't work just yet. Fixed an actual regression that the test suite detected -- moved some defines to Defines.php where they will be loaded consistently.
* Seems like an opportune time to introduce "@addtogroup Media" documentation tags.
* Merge "@addtogroup Metadata" (used by Exif.php) into "@addtogroup Media".
* Few more moving comment blocks to above classes.
* Deprecated $wgUseImageResize, thumbnailing will be enabled unconditionally.
* Fixed interaction of page parameter to ImagePage with the HTML file cache
* Improved error reporting for image thumbnailing
* Fixed MIME type for SVG files, will be silently changed from image/svg to image/svg+xml after loading from the database.
* Workaround for djvutoxml bug #1704049 (poor performance). Use djvudump instead.
* Fixed odd behaviour in ImagePage on DjVu thumbnailing errors
* Improved error reporting for image thumbnailing
* Added sharpening option for ImageMagick thumbnailing
* Removed Image::selectPage(), added page parameters to getWidth() and getHeight(), deprecated Image::renderThumb() and Image::getThumbnail()
* Changed default contents of img_metadata to empty string instead of a:0:{}
* Moved responsibility for respecting $wgGenerateThumbnailOnParse from the UI to Image.php
* Convert "$dbw =& wfGetDB( DB_MASTER );" --> "$dbw = wfGetDB( DB_MASTER );"
* convert "$skin =& $wgUser->getSkin();" --> "$skin = $wgUser->getSkin();"
For the time being have not changed the function definitions of wfGetDB() or User::getSkin() [i.e. they are still both return-by-ref], so as to ensure the interface does not change for extensions [some of which may still be trying to run on PHP4 environments]. However presumably at some point this can be changed too.
Also includes tiny tweak to newlines in parserTests - will show 1 rather than 2 newlines between the "Reading tests from" strings when in quiet mode.
* Allow setting the skin object that ImageGallery will use; needed during parse operations (the skin must come from the ParserOptions, not $wgUser)
* Prod a few skin files and increment some cache-smashers
