GPU max frequency always 0 under Win32 D3D

[Withaust]

It happens for both discrete and integrated video cards with DX detection for some reason.

Yes:

infoware/src/gpu/d3d.cpp

Lines 60 to 63 in 29538ab

	devices.push_back({vendor_from_name(device.vendor_name), device_name, adapterdesc.DedicatedVideoMemory, adapterdesc.SharedSystemMemory,
	// TODO: there's purportedly (https://en.wikipedia.org/wiki/Windows_Display_Driver_Model#WDDM_2.3)
	// a Windows API for getting the max clock, but I haven't been able to find it or use it
	0});

This is available through OpenCL only at present. I don't immediately see a way to see this documented in the D3D API either.
