Can be combined with the style structures.
<!> If used needs to be defined for implementation and header <!>
NK_INCLUDE_DYNAMIC_SOFT_KEYBOARD
Defining this means that when a textedit field is begun editing,
nuklear will look for ctx->open_keyboard() and ctx->close_keyboard()
functions to call. Set these functions during nk_context initialization
in your backend. This is "DYNAMIC" because a PC soft keyboard is always open,
but a mobile device will show and hide the soft keyboard dynamically
as needed.
NK_BUTTON_TRIGGER_ON_RELEASE
Different platforms require button clicks occuring either on buttons being
pressed (up to down) or released (down to up).
