- `fullscreenFlags` available for those who want an alternative
to `withFullscreen` without reinventing too much.
- Raw.begin got `open` and `flags` arguments.
- Added Raw.setNextWindowFullscreen combo block.
This handles the remaining enum types in the headers that aren't in the enums section.
It also automatically handles adding all the enumerations to the inline-c context types table, and a small improvement to the display of parse error messages.
Just doing a little cleanup:
* some functions were not exported,
* some functions were missing the initial | for their documentation,
* add types to the ImGui Context instead of coercing to int. This is more robust, in case upstream changes any of the larger enums to be 64 bits instead of 32 for instance
