104415d5c3 win-capture: Fix hook bug that could cause crashes
I had this issue where IDXGISwapChain::ResizeBuffers would fail in the
hooks, causing games to crash when they resized their backbuffers
because ResizeBuffers would return an 'invalid call' HRESULT value.  In
the ResizeBuffers documentation it says that it will only happen if a
backbuffer currently has any outstanding references, but there's no way
this would happen unless ResizeBuffers internally calls Present or vise
versa.

After ResizeBuffers has been called, the very first call to Present will
somehow seemingly invalidate and/or destroy the current backbuffer.
It's very strange, but that seems to be what's going on, at least for
the game I was testing.  So if you are performing a post-overlay
capture, then you must ignore the capture on the very first call to
Present.

It's Microsoft's code so you can't really know what's going on, you just
have to work around these strange issues seemingly in the dark.

8b59b606c5 win-capture: Use right call type for hook funcs
Although STDMETHODCALLTYPE is technically WINAPI (__stdcall), it's best
not to make any assumptions.

a5872955f4 win-capture: Add graphics-hook library
This library is a completely refactored and rewritten version of the
original graphics hook.  The code is more clean, readable, and has a
variety of new features, such as scaling and forcing memory capture.

Currently, only D3D9, 10, and 11 are implemented.  (This commit may be
updated on this branch)
