NeoBrainX 91d540ad67 DX11: 
Fix all remaining window resizing issues.
Implement screenshot functionality (doesn't seem to work completely, yet).
Assign debug names to (hopefully) all remaining device objects.
Flush the GPU's command buffer in Close() to make the ReportLiveDeviceObjects output clearer.
