* Patch from Michael Fox to set the normal angle (was fixed at 80 before)

Browse Source 
* Fixed another face clipping bug (some artifacts still when using screen aligned faces)
* Removed Soften and Warp buttons on the panit panel since they are not used for projection painting
* added do_versions to initialize bleed and normal values
