wddm modes for QXL device
Disclaimer: WDDM driver for Windows 10 is not supported by RedHat yet. This bug report was created just for keeping track. The status of WDDM driver maybe will be changed in the future.
Bug info: Console option provides "Enable WAN options" checkbox. This option can be activated by user for low band-wish networks. This option does different adjustments for SPICE protocol. One option among this adjustments is to drop down colors depth from 32 bits to 16 bits. The problem is that WDDM driver doesn't support 16 bit color depth.
How reproducible: always.
Steps to Reproduce:
1. Log in to User or Admin portal.
2. Have a Windows 10 with installed WDDM driver for QXL device.
3. Go to "Console option" for this VM.
4. Activate checkbox: "Enable WAN options".
5. Invoke console to this VM.

This option doesn't have any effect on remote virtual desktop. Remote desktop has 32 bits colors regardless above option.
