- file-to-memory save - incremental difference steps (compression) everthing has been tightly coded to use minimum of memcpy or allocs. In fact this system works with a single full buffer (=file) in memory, and undosteps as differences from it. Speed gain is factor 4-8 faster. I've added it in CTRL+ALT+T timer menu for a test. Please note the gain is especially in the undo-storing, not in retrieving undo. Also new: file read option to skip UI read (file menu). This now also is default for the undo system.
