Fix T47038: Particles in Particle Edit Mode get added in completely wrong location. It also fixes another issue (crash) related to symmetric editing. Quite involved, we (try to!) fix complete broken logic of parts of particle code, which would use poly index as tessface one (or vice-versa). Issue most probably goes back to BMesh integration time... This patch mostly fixes particle editing mode: - Adding/removing particles when using generative modifiers (like subsurf) should now work. - Adding/removing particles with a non-tessellated mesh (i.e. one having ngons) should also mostly work. - X-axis-mirror-editing particles over ngons does not really work, not sure why currently. - All this in both 'modes' (with or without using modifier stack for particles). Tech side: - Store a deformed-only DM in particle modifier data. - Rename existing DM to make it clear it's a final one. - Use deformed-only DM's tessface2poly mapping to 'solve' poly/tessface mismatches. - Make (part of) mirror-editing code able to use a DM instead of raw mesh, so that we can mirror based on final DM when editing particles using modifier stack (mandatory, since there is no way currently to find orig tessface from an final DM tessface index). Note that this patch is not really nice and clean (current particles are beyond hope on this side anyway), it's more like some urgency bandage. Whole crap needs complete rewrite anyway, BMesh's polygons make it really hard to work with current system (and looptri would not help much here). Also, did not test everything possibly affected by those changes, so it needs some users' testing & validation too.

Depsgraph: New dependency graph integration commit This commit integrates the work done so far on the new dependency graph system, where goal was to replace legacy depsgraph with the new one, supporting loads of neat features like: - More granular dependency relation nature, which solves issues with fake cycles in the dependencies. - Move towards all-animatable, by better integration of drivers into the system. - Lay down some basis for upcoming copy-on-write, overrides and so on. The new system is living side-by-side with the previous one and disabled by default, so nothing will become suddenly broken. The way to enable new depsgraph is to pass `--new-depsgraph` command line argument. It's a bit early to consider the system production-ready, there are some TODOs and issues were discovered during the merge period, they'll be addressed ASAP. But it's important to merge, because it's the only way to attract artists to really start testing this system. There are number of assorted documents related on the design of the new system: * http://wiki.blender.org/index.php/User:Aligorith/GSoC2013_Depsgraph#Design_Documents * http://wiki.blender.org/index.php/User:Nazg-gul/DependencyGraph There are also some user-related information online: * http://code.blender.org/2015/02/blender-dependency-graph-branch-for-users/ * http://code.blender.org/2015/03/more-dependency-graph-tricks/ Kudos to everyone who was involved into the project: - Joshua "Aligorith" Leung -- design specification, initial code - Lukas "lukas_t" Toenne -- integrating code into blender, with further fixes - Sergey "Sergey" "Sharybin" -- some mocking around, trying to wrap up the project and so - Bassam "slikdigit" Kurdali -- stressing the new system, reporting all the issues and recording/writing documentation. - Everyone else who i forgot to mention here :)
