I wouldn't say that. It's just a few lines of code in a handler to draw a
Theme button. Or you can just call DrawNextEventHandler() to draw it as long
as the system is just drawing a blank button anyway.

You can use an IconRef created from an IconFamilyHandle (.icns file or
'icns' resource) which consists of a single (16x16) icon that has your 12x12
image in its center and it will work fine in a bevel button. I use this for
some 10x10 icons and it works just fine. I'm not sure why you think this
isn't an option.
