Incorrect returned value in nk_group_scrolled_offset_begin

[krys-g]

As of version 4.10.6, compiling nuklear.h with #define NK_INCLUDE_STANDARD_BOOL yields the following warning:
enum constant in boolean context [-Wint-in-bool-context]

The issue stems from NK_API nk_bool nk_group_scrolled_offset_begin():

        if (f & NK_WINDOW_CLOSED)
            return NK_WINDOW_CLOSED;
        if (f & NK_WINDOW_MINIMIZED)
            return NK_WINDOW_MINIMIZED;

Given that the function is expected to return "true(1) if visible and fillable with widgets or false(0) otherwise", I'm guessing the two return should be merged into a single return false instead? Currently the conversion from the nk_window_flags enum to bool would return true.
