Global context GImGui is not available in C API

[memononen]

This code seems to be omitted from the C API:

#ifndef GImGui
extern IMGUI_API ImGuiContext* GImGui;  // Current implicit context pointer
#endif

I ran into it while trying to implement editable selectable from here: ocornut/imgui#2718 (comment)

I'm not sure if that would require some cast magic to work. I guess a getter function could work too.

This works as workaround:

ImGuiWindow* win = ImGui_GetCurrentWindow();
ImGuiContext* g = win->Ctx;

Note that you can call ImGui_GetCurrentContext() directly too.

Awesome, missed that.

Should I close the issue, or is it still valid? Looks like at least IMGUI_DEBUG_LOG_FONT tries to use GImGui.
