The latest dev build (dev16215-9215) includes many changes in dmap: 5562, 5488, 5486 The main goal of these changes is to make dmap faster. In most cases it meant writing a faster version of some small piece of code. There is one major exception: I had to write a brand new algorithm for optimizing polygon triangulations (~1200 LOC). I used two well-known FMs to track progress. Here is the total time improvement: Painter's Wife (city): 8:10 -> 1:28 No Honor Amon
