cff64ee7d3 dxgi: cache shared handles instead of re-creating them
This will cache up to 10 handles, in practice I have never seen DXGI
return anything but the same resource each time but we allow for more
anyway should MS change something in the future.

Should the cache get over filled it is disabled entirely and we revert
to the original behaviour.

b117bbafe5 [host] dxgi: add ability to capture OutputDebugMessage
This is how Direct3D 12's debug layer outputs messages. Normally, these
are read by the debugger, but we want them logged instead.

3d0a8f6987 [host] dxgi: fix frame damage method parameters
The buffer input sizes to the `IDXGIOutputDuplication` methods are measured
in bytes. This dramatically increases the number of dirty/move rects that
can be handled.

2f8b139131 [host] windows: set DwmFlush default to off
This new feature while helps on some systems, others using freesync or
higher refresh rates where the capture can't keep up will limit to
fractions of the refresh rate. Better to disable and allow users to
opt-in.

92f27cc0f0 [host] dxgi: use DwmFlush to sync to presentation interval
This change reduces the host GPU and CPU load by a large margin
improving guest system performance along with removing latency spikes
when moving the mouse. This is default enabled but can be disabled with
the new option `dxgi:dwmFlush=no` as it limits the capture rate to the
refresh rate of the guests output which may not be desireable.

9bded74543 [host] dxgi: use CopySubresourceRegion when possible
This commit adds damage tracking to the DXGI textures, and only copies the
damaged areas to the textures with ID3D11DeviceContext::CopySubresourceRegion.

The sleep logic in waitFrame makes it difficult for this to reduce the
latency, but removing it shows significant improvements (6-7 ms to ~3 ms)
when a tiny portion of the screen is damaged, while showing no difference on
full screen damage.

3d29967a8d [host] dxgi: copy only damaged regions to IVSHMEM
This implementation uses a line sweep algorithm to copy the precisely the
intersection of all accumulated damage rectangles, ensuring that every
pixel is copied exactly once, and no pixel is ever copied multiple times.
Furthermore, once a row has been swept, we update the framebuffer write
pointer immediately.

e477663a7e [host] app: allow the capture interface to select async or sync mode
While it's correct for DXGI to use a asyncronous waitFrame model, other
capture interfaces such as NvFBC it is not correct. This change allows
the capture interface to specify which is more correct for it and moves
the waitFrame/post into the main thread if async is not desired.

This change adds an average function to time how long it takes the GPU

f2c0b8c0b4 [host] allow user to select capture backend
This commit introduces a new option, app:capture, which can be set to
either DXGI or NvFBC to force the host application to use that backend.

This is very useful for testing DXGI on Quadro cards, which would default
to running with NvFBC.
