* This API is now intended to be forward and backward compatible as much
as possible. Meaning applications should be able to run without
changing on many RenderDoc versions after the one they are built
against without breaking.
* All function pointers are fetched at once in one versioned GetAPI()
function, to save on constant GetProcAddress/dlsym'ing.
* Otherwise, it's largely similar to the previous API.
* Has a couple of limitations - won't check deferred context or
NO_OVERWRITE Map()s except in a captured frame. This could in theory be
implemented but it'd be complex and I don't want to complicate/break
the normal path.
* When an overrun is detected, a messagebox pops up to block the thread,
and if you hit yes, it will debugbreak.
* These capture options used to be propagated through from the C++ struct
when there was a C++/CLI dll used for interop between C# and C++. Now
that we use P/Invoke this needs to be added back so a couple of default
options can be enabled
