72b25b99bc [host] add new D12 capture interface 
Note, this capture interface is not yet feature complete but does seem
to be stable.

34e8a2255e [host] dxgi: d3d12 now writes direclty into ivshmem 
This is still incomplete as d3d12 doesn't have any proper sync with the
captured frame and as such is still not suggested for general usage. This
change though is monumental for this project as it removes a full memory
copy reducing bandwidth consumption enormously.

d44fc36fc4 [host] DXGI: stop rescaling RGB24 texture height 
For the moment, this just increases texture memory usage, but does not
affect behavior.

In a future commit, I will modify the shaders to not pack data across
rows, in order to enable damage copies.

c29404eea6 [host] DXGI: fixed swapped rows and cols variables

200b7b732c [host] dxgi: properly convert HDR16 to HDR10 
DXGI doesn't take into account the SDRWhiteLevel that has already been
applied to the monitor when it converts to HDR10 which results in clipping.
This change set implements a HLSL shader to reverse this while at the same
time converting to HDR10.

This is still not perfect but far better then doing nothing.

e4a8424fad [host] nvfbc: fix ARGB10 support 
There is no performance penalty to using ARGB10 as it's still a 32-bit copy per

this work for both SDR and HDR.

3134ec84de [host] dxgi: add support for downsampling the capture before sending 
This is an experimental & incomplete feature for those using

Unfinished! Has issues with damage tracking and currently can not
be configured. Only dx11 has been tested at this point, everything
else will likely have problems/crash.
