[Bf-committers] Updated BMesh Merge Proposal

[Mikhail Raisler]

"Propose to write edge data into files so they load in 2.60 and older, but add logic into BMesh that knows to ignore these edges.
Also, this extra edge data will slow down saving so it will be disabled for undo which also uses save code - Campbell"

So you guys wrote new particle system without backwards compatibility, you wrote new anim sys without backwards compatibility, you wrote new python api without backwards compatibility....
And now when bmesh edge data is so heavy, you wanna make it more heavy make backwards compatibility... I think it's a bad idea.
