[LOGGED] Incremental update to 3D actors - Isadora feature request

[bonemap]

Hi,

It would be great to see an incremental update or refresh of the 3D space and modules in Isadora. 

Some of the attributes screaming for an update and top of my list are: 

1/a depth map feature

2/expanded file format compatibility

3/update to z index, back face and layering attributes

Best Wishes

Russell
