Memory saving for large renders:
New option "Save Buffers", in first Output panel of renderbuttons, will not allocate all render buffers, but instead save the rendered tiles to exr. For each scene rendered, a single exr file then is created. After rendering, the files get read, and only then the memory allocation is done. The exr files are saved in the temp dir (from user settings), and have names derived from the filename+scene name. That way these buffers remain relatively unique, and can be re-used later too. Saving all render-layers and passes in a single file (as F3 command) will be done later. Also reading back the current muli-layer exr files is not supported yet (will read black). The purpose is that these files then can be used as input for the Compositor. One fun thing I added; after rendering once with this option, close Blender, and restart it. If you have a Composite set up press 'R' on an active RenderResult node. This will refresh the node(s) and load the exr, so you can composite again without a re-render.
