[sldev] Avatar mesh/morph exporter/importer

[Mike Monkowski]

I've added a patch to http://jira.secondlife.com/browse/VWR-6199 that 
does not do all of what the issue asks for, but it does do some 
interesting things.

1. It provides a menu structure created by selecting "Meshes And 
Morphs..." from the Advanced->Character menu.
2. Its primary purpose is to allow machinimators to modify the Emote 
morphs (using a 3D graphics editor) to build more expressive avatars.
3. A secondary purpose is to allow residents to export their current 
appearance meshes to 3D graphics editors in order to map textures 
better. I'd also be interested to see if it's possible, using other 
tools, to then import the mesh as a sculpty to make a mannequin.

The patch is applied to version 1.21.6 of the source code.

Since I don't distribute a binary, I was hoping I could entice someone 
who does to incorporate this patch into their viewer.  You can find more 
details at the link given above.
