== imagebrowser ==
Initial commit of imagebrowser in trunk. BIG COMMIT! Main changes: * completely reworked imasel space * creation and storage of the preview images for materials, textures, world and lamp * thumbnails of images and movie files when browsing in the file system * loading previews from external .blend when linking or appending * thumbnail caching according to the Thumbnail Managing Standard: http://jens.triq.net/thumbnail-spec/ * for now just kept imasel access mostly as old imgbrowser (CTRL+F4, CTRL+F1) a bit hidden still. * filtering of file types (images, movies, .blend, py,...) * preliminary managing of bookmarks ('B' button to add, XKEY while bookmark active to delete) More detailed info which will be updated here: http://wiki.blender.org/index.php/User:Elubie/PreviewImageBrowser Places that need special review (and probably fixes): * BLO_blendhandle_get_previews in readblenentry * readfile.c: do_version and refactorings of do_library_append * UI integration TODO and known issues still: * Accented characters do not display correctly with international fonts * Crash was reported when browsing in directory with movie files * Bookmark management still needs some UI work (second scrollbar?), feedback here is welcome! Credits: Samir Bharadwaj (samirbharadwaj@yahoo.com) for the icon images. Many thanks to everyone who gave feedback and helped so far!
