I guess I neglected to mention that the reason for bothering to add 3D paint tools is that I worked out how to enlarge the projected textures.  They are no longer locked into a default 256x256 size and can now be as large as you like.  I've only set it up to handle up to 1024, reasoning that a 600 square source image can only be usefully enlarged so much, but a user can add blank templates as png to enable larger sizes.

I don't know if that manages to make any of the resulting textures useful to anyone, but with that possibility in mind, I've added symmetry tools for the projected texture and those paint tools.  Here's a quick glimpse of sym-tests for 1024 textures.
