Add some widget on titlebar

[OmhaRobin]

Version/Branch of Dear ImGui:

Version: 1.87
Branch: master

Back-end/Renderer/Compiler/OS

Back-ends: imgui_impl_glfw.cpp + imgui_impl_opengl3.cpp
Operating System: win10

My Issue/Question:

How can I add a input widget by ImGui::InputText() on the right of titlebar as the figure shown? I have let the window has the same size as the GLFW window and used ImGui::Begin("##my window", nullptr, ImGuiWindowFlags_NoCollapse | ImGuiWindowFlags_NoResize); to change the titlebar settings. Please ignore the texture image on the left.

ImGui::RenderWindowTitleBarContents(): Should I change this function to put a texture image or input widget on titlebar?

I guess you would generally need to push a clip rect, see what BeginMenuBar() is doing, you'd want to do something similar.

Also see #5115 (which I left answered in spite of being well crafted, apologies to Simon). And #4385. #4137, #3882.

@ocornut Thank you, I'll try what you said.
