message: Demo: Comment about 'static' and some tweaks
diff: // Everything in this file will be stripped out by the linker if you don't call ImGui::ShowTestWindow().
  // During development, you can call ImGui::ShowTestWindow() in your code to learn about various features of ImGui. Have it wired in a debug menu!
  // Removing this file from your project is hindering access to documentation for everyone in your team, likely leading you to poorer usage of the library.
  -
  // Note that you can #define IMGUI_DISABLE_TEST_WINDOWS in imconfig.h for the same effect.
  // If you want to link core ImGui in your public builds but not those test windows, #define IMGUI_DISABLE_TEST_WINDOWS in imconfig.h and those functions will be empty.
  // For any other case, if you have ImGui available you probably want this to be available for reference and execution.

  // Thank you,
  // -Your beloved friend, imgui_demo.cpp (that you won't delete)
  +// Message to beginner C/C++ programmer about the meaning of 'static': in this demo code, we frequently we use 'static' variables inside functions.
  +// We do this as a way to gather code and data in the same place, make the demo code faster to read, faster to write, and smaller. A static variable persist across calls,
  +// so it is essentially like a global variable but declared inside the scope of the function.
  +// It also happens to be a convenient way of storing simple UI related information as long as your function doesn't need to be reentrant or used in threads.
  +// This may be a pattern you want to use in your code (simple is beautiful!), but most of the real data you would be editing is likely to be stored outside your function.
