Hello,

First, thanks @Gnimuc for this package, Julia is lacking UI lib and having this one can help.

After installing latest master version of Nuklear.jl

I'm facing an error

I'm using Mac OS X 10.13.6

Any idea?

Kind regards

a helper function to get the font handle

I need a helper function to get the font handle.
see
https://github.com/vurtun/nuklear/blob/master/nuklear.h#L3810

for example,

struct nk_user_font* nk_font_handle(struct nk_font *font) {
    return &font->handle;
}

this helper function to be added in
https://github.com/Gnimuc/NuklearBuilder/blob/master/wrapper/helper.c

Update Project.toml with external package version bounds

Right now since there are no compatibility bounds, I'm unable to upgrade GLFW to v3

Fonts + high DPI

Fonts look pretty bad and elements are very small on a high dpi display.
Those issues are likely related!

Fonts seem like they can look nice:
vurtun/nuklear#69

I guess I can also answer my second question:
vurtun/nuklear#283
:D
It's pretty easy to figure out the dpi of a screen with GLFW, so maybe we can do that and scale the demo accordingly
