No this is fine, but remind me if I accidentally skip over one.
By the way, I'm a little hesitant to do too much work on the bindings
since wxWidgets 3.0 uses doxygen and some sort of stripped down
headers for their docs. In order to keep the bindings updated I'll
probably want to switch to that format and have to completely rewrite
the binder.

The parser probably gags on the extra (). I think a reasonable hack
would be to have something like this as a replacement.
#define wxZeroPoint wxPoint(0,0)

Hopefully fixed, I added code to cast the wxCharBuffer (unsigned
char*). However, it does have to be "const unsigned char*" since you
cannot take ownership of the string from Lua. I think wxImage wrappers
have an override that shows how to set the image data from a Lua
string.

Probably ok to just remove the friend word as you did. What does it
mean to have a friend function like this in C++?

I'll look into this.

You can't get & references like this in Lua since it only has double
valued numbers. But, I've fixed the bindings to not put the extra &
before self->GetValueRef().
