This would only work in very limited circumstances. I think you're confusing
the theme property itself and its contents. To make an analogy with
dereferencing a pointer, you have these levels:
(Theme object/property IDs)
---pgThemeLookup--->
(Property content
I have what is likely a naive question. If there could be such
a solution where a pointer to a theme property could be established,
why couldn't loading a new theme just generate the same id as
the one being reloaded? In other words, if I have a theme object
foo, it gets generated a handle, right?
