Still not working with docking branch 1.76WIP

Merged in master

I'm really confused, this is all output in the SAME cimgui.h instead of cimgui_internal.h ?

This is a recipe for disaster where people would

1. get confused by the mixture of public facing and internal functions in the same file.
2. accidentally use functions that will break in future versions.

Any reason for not outputting a separate cimgui_internal.h file?

#108 (comment)

Althought I could try to put it in separated files after the parsing

2\. accidentally use functions that will break in future versions.

This is independent from the fact that they are in the same header, as the bindings users dont know from which header they come.

I understand this may not be easy to implement but shouldn't we at least have an open issue for it?

I think that along with #139 this is very important to distinguish those into a cimgui_internal.h file.

How can we help?

While looking at cimgui.h today I came with the idea that if cimgui_internal.h is more work to achieve, in the meantime MAYBE it would be possible to move the internal stuff AT THE END of cimgui.h and behind a user accessible ifdef?
I don't know if that's simpler to implement, just an idea.
