Nuklear+ (read as "Nuklear cross") is a front-end overlay for Nuklear GUI library.

Preprocessor constants:

NKC_IMPLEMENTATION - define this constant in one C-file in your project, or use nuklear_cross.c
NKC_DISABLE_DEFAULT_FONT - if set, the default Nuklear font will not be included. Size reduce
NKC_DISABLE_IMAGES - do not include stb_image and images function. Size reduce
NKC_USE_OPENGL=3 - use OpenGL 3 instead of 2 in OpenGL-based frontends
NKCD=x - choose Nuklear+ fronend driver: Frontend choose (with OpenGL 2/3):
NKC_SDL - SDL2
NKC_GLFW - GLFW3
NKC_XLIB - X11/Xlib Non-OpenGL frontend:
NKC_GDIP - GDI+ (Windows only). The minimal size. Resulting picture differs from OpenGL!
NKC_XLIB - X11/Xlib. No font loader!

Not all Window modes are implemented in each frontend.
