I have a png image with an area "masked out" in my pain program.  I want to
apply it as a tatoo on top of an existing texture.  Any pointers?

I thought I tried exactly that, and it showed me "gray" where the PNG image
was "masked out".   Perhaps I need some other format than PNG??

I use TGA but PNG is fine.

An other way: try extracting your mask towards a new image and use it for an
image_pattern

Try to apply that PNG mask to simple plane as texture. Is area outside mask
transparent? Adjust scene to be sure everything is in visible space.
Knowing SDL and seeing images in p.b.i could help in helping.

Thanks for all the help.
Somehow it worked with a "white" background and the proper mask.
It didn't work with a "nonexistent" background or a background that was
displayed as a light grey and white checkerboard by my paint program.

And was there some trick--besides going to object texture, to get it to only
lie on one side of the object?

It depends on what kind of object and what projection mode you use.
See manual section 6.7.12.7.2
If it fails, see uv_mapping
section 6.7.7
And ask again :)
