Window dimensions are always reported as 400x400

[Octogonapus]

GetWindowSize(), GetWindowWidth(), and GetWindowHeight() always report 400 regardless of the provided window_size to render and regardless of the true window size when resizing it at runtime. I could reproduce this by adding @show CImGui.GetWindowWidth() here on the latest master.

The problem is the location of the calls to GetWindowSize(), they (along with all other CImGui calls) have to be within a Begin()/End() block to work properly. If you put it outside of that then it looks like you get the window size of the default debug window:

See for example: ocornut/imgui#4404 (comment)

If you put those calls within a window block then you should get the right sizes. Alternatively, if you're really looking for the GLFW window size you probably want unsafe_load(GetIO().DisplaySize).

Thank you!
