  • I F5'd it on a version with this function and it still works

Detailed Description of the Pull Request / Additional comments

I keep forgetting that anything in the WPF control needs to keep working on Win7. Or more specifically... I remember this fact for the DX renderer, but not for the render thread base. Oops. Turns out this particular convenience method to set thread descriptions for visibility inside the debugger (to make my life easier) only works down to 1607 (see https://docs.microsoft.com/windows/win32/api/processthreadsapi/nf-processthreadsapi-setthreaddescription). Since it's just a debugging convenience... skipping it entirely when the procedure is not found should be fine. Also I don't try to load kernel32.dll and just get the handle of the existing module (which per the remarks at https://docs.microsoft.com/windows/win32/api/libloaderapi/nf-libloaderapi-getmodulehandlew will not increment the module reference count) because kernel32.dll pretty much has to be there or we're already in hot water.
