When window capture is not capturing a window, don't try to find the
window every frame. Instead, just check once per frame. The process of
finding a window has a lot of checks and requires a surprising amount of
processing.
Operating systems don't report monitors from 0, so OBS shouldn't
either. This avoids user confusion when display capture doesn't work.
This does not change monitor count internally.
The GDI+ based Text Source actually uses Premultiplied Alpha. The edges
of the fonts are therefore incorrectly blended, causing ugly artifacts
especially if bright text above a bright background is used. Here's an
image comparing the new text blending (left) to before (right):
Additionally, the game capture has the same problem, so premultiplied
alpha is used there as well now.
Makes Visual C runtime libraries consistent across
Debug/MinSizeRel/Release/RelWithDebInfo, rather than just changing those
flags for RelWithDebInfo. Also adds /Zl for statically linked
libraries.

Occasionally users accidentally select the following applications built
into Windows 10 using game capture, which cannot be captured.
This PR simply hides them from the game capture list.
The latter takes up 6 entries in the dropdown.
LockApp.exe - the lock screen which doesn't run in user space
WindowsInternal.ComposableShell.Experiences.TextInput.InputApp
Re-fetch texture when cursor's either width or height changed.
When the cursor icon changed and the new one has the same width or height,
it may not recreate the texture and thus cause memory access violation.
When drawing cursor to window capture area - use actual resource width
and height instead of system metric values for icons. Fixes an issue
where under rare circumstances, certain cursors would not draw at the
correct size.

Fixes an issue where align_pos could be smaller than
sizeof(struct shmem_data), potentially overwriting memory of the header.

Makes it a bit more clear this option shouldn't be used unless you're on
SLI/crossfire.
In the future, something should be put in to the program that detects
laptops and warns on how to set up their adapter for efficient capture.

If the target process re-creates its D3D context, the game capture tick
can trigger before the capture is setup, in which case OBS gets a
CAPTURE_RETRY message. However with the memory capture method, it
continues to try and copy from the shared memory pointer which is no
longer valid, resulting in a crash. The fix uses the old texture until
the next tick at which point the new capture should be ready for use.
Windows SDK 10.0.16299.0 defines these structures as part of winternl.h
but using different types and names. Unfortunately there's no macro to
detect the SDK version, so to avoid conflicting with newer / older SDKs
the OBS structs have been renamed.
"Life is Feudal: Your Own" will use Direct3D to render the game, then
OpenGL to render its in-game menus, which causes a conflict with itself.
This specifically blacklists the game from capturing OpenGL to prevent
that from happening.
When hooking DXGI-based graphics programs in the hook, the first hook
point is IDXGISwapChain::Present. To be able to initiate a capture, a
pointer to the device context that created the swap chain is required,
which can be retrieved via IDXGISwapChain::GetDevice. Determining
whether the device context was D3D10 or D3D11 has always been somewhat
of an issue due to D3D10 and D3D11 being nearly identical, as well as
their interoperability/interchangeability. The GetDevice function would
first be called with the UUID of ID3D10Device, then if that failed,
the UUID of ID3D11Device.
However, with certain specific D3D11 games, GetDevice would for some
unknown reason succeed with the UUID of ID3D10Device, which would cause
capture to fail. (Conversely, attempting to call GetDevice with the
UUID of ID3D11Device on a device that's actually ID3D10Device would
always succeed, so reversing the order of the test was not an option).
There were originally three known D3D11 games that would erroneously
succeed when querying a D3D10 device interface: Call of Duty: Ghosts,
Just Cause 3, and theHunter: Call of the Wild. All other known D3D11
games would work correctly. Because it was only these three games, a
hack was originally implemented in the form of an executable exception
list that would force them to capture D3D11.
Unfortunately, Oculus games are now failing under the same circumstance
as well, so a simple hack will no longer work. To fix this, a more
reliable method of detecting which context it is had to be discovered:
simply check the feature level using ID3D11Device::GetFeatureLevel. If
the feature level is D3D_FEATURE_LEVEL_11_0 or D3D_FEATURE_LEVEL_11_1,
the device is definitely a D3D11 device. Otherwise, continue the tests
as they were before. Successfully tested with many D3D10 games, many
D3D11 games, and especially those three D3D11 games that previously were
detected as D3D10 erroneously.
