tile cache code in imbuf, but it is not hooked up to the render engine. Imbuf module: some small refactoring and removing a lot of unused or old code (about 6.5k lines). * Added a ImFileType struct with callbacks to make adding an file format type, or making changes to the API easier. * Move imbuf init/exit code into IMB_init()/IMB_exit() functions. * Increased mipmap levels from 10 to 20, you run into this limit already with a 2k image. * Removed hamx, amiga, anim5 format support. * Removed colormap saving, only simple colormap code now for reading tga. * Removed gen_dynlibtiff.py, editing this is almost as much work as just editing the code directly. * Functions removed that were only used for sequencer plugin API: IMB_anim_nextpic, IMB_clever_double, IMB_antialias, IMB_gamwarp, IMB_scalefieldImBuf, IMB_scalefastfieldImBuf, IMB_onethird, IMB_halflace, IMB_dit0, IMB_dit2, IMB_cspace * Write metadata info into OpenEXR images. Can be viewed with the command line utility 'exrheader' For the image tile cache code, see this page: http://wiki.blender.org/index.php/Dev:2.5/Source/Imaging/ImageTileCache
