9ce4990793 [host] capture: pass frameIndex to capture backends 
This allows capture backends to track damage made to each frame.

f274bec8fc [host] dxgi: compute damage rectangles from moved rectangles 
This is untested in that I don't have a Windows 8 VM where move rects
are supplied, but seems sound.

411a6b1e49 [host] windows: add delayExecution function for more accurate sleeps 
This change not only exposes and allows use of NtDelayExecution, but
also moves the code to set the system timer resolution.

789ee70674 [host] dxgi: print out the adapter details earlier 
Before we try and perhaps fail to init DXGI, we should print out what
the device is so that when there is an error report we can immediately
see if the user has the QXL device attached still.

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.

78b8e2a73c [host] windows: make D3DKMTSetProcessSchedulingPriorityClass global 
Testing shows that `D3DKMTSetProcessSchedulingPriorityClass` has a
positive performance impact for NvFBC as well as DXGI, as such always
try to boost the priority for the windows host.

d36c4f0e83 [host] kvmfr: allow the frame size to exceed the available memory 
This change allows the host to still transmit a frame that is truncated
if the IVSHMEM size is too small to allow for a full frame.

f02d61d665 [host] dxgi: sleep until it's close to time to map 
This change adds an average function to time how long it takes the GPU
to copy and map the texture, and then uses this average to sleep for 80%
of this average lowering CPU usage and potentially decreasing lock
contention.

0d9b0bd367 [host] dxgi: increase maxTextures default to 4 
Testing shows that at high frame rates the default of 3 is hampering
performance, increasing this to 4 yields a substantial performance
improvement.

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.

cac454d9cf [host] dxgi: reverse the rotation angle. 
This is undocumented however testing yields that DXGI DD reports the
inverse rotation. Research shows that this is because of a difference in
coordiate spaces.

a46a3a2668 [all] use explicit void parameter lists 
This makes it a compile-time error to call a function that semantically
takes no parameters with a nonzero number of arguments.

Previously, such code would still compile, but risk blowing up the stack
if a compiler chose to use something other than caller-cleanup calling
conventions.

7e362050f7 [all] update KVMFR to provide cursor hotspot information 
This commit bumps the KVMFR protocol version as it adds additional
hotspot x & y fields to the KVMFRCursor struct. This corrects the issue
of invalid alignment of the local mouse when the shape has an offset
such as the 'I' beam.
