Missing Bindings: format string arguments for ImGui.text and ImGui.coloredText

What part of the binding has gaps?

Dear ImGui

What is missing?

In Dear ImGui, Text and TextColored accept a format string and varargs - format string arguments. According to ImGui.java, these are hardcoded to NULL:

    private static native void nText(String text); /*MANUAL
        auto text = obj_text == NULL ? NULL : (char*)env->GetStringUTFChars(obj_text, JNI_FALSE);
        ImGui::Text(text, NULL);
        if (text != NULL) env->ReleaseStringUTFChars(obj_text, text);
    */

Use case: measuring text size to position it before rendering. calcTextSize expects a pre-formatted string. But text and textColored still expect format strings, even though it is not possible to pass format string arguments. So if the string contains, for example, a % character, it needs to be encoded as %% - and that cannot be directly passed to calcTextSize - it will return incorrect value.

I can think of 2 possible solutions, depending on how difficult it is to bind varargs methods:

1. allow to pass varargs (Object...) to text and textColored methods
2. instead of ImGui::Text(text, NULL), invoke ImGui::Text("%s", text)

Given that the 2nd approach would break existing implementations, the 1st one would be much better
