With one vertex behind the near plane, the GE splits the remaining quad from
the vertex before the clipped one (gpu/probe exp43, exp44, as in SoftGPU's
Clipper.cpp). The other diagonal could put a far off-screen near-plane vertex
in both halves, so range culling dropped the whole triangle: the floor in
#16131's box test vanished. The index generator reverses triangles to flip
culling, so the batch's order is passed along.
Triangles entirely beyond the far plane are now culled even when in front of
the near plane, with the cull-distance epsilon, so z/w = 1.0000172 (exactly
1.0 to the GE) still counts as inside.

The restored draw context can be a new device, so the cached pointers
could go stale.

Map fails after device removal, leaving pData garbage. Skip the upload or
draw instead of writing through it.

The draw engine is created on the loader thread while the UI thread may
already be rendering and invoking the callback.

The shader creation helpers returned S_FALSE when compilation produced no
bytecode - but S_FALSE is a success code, so the FAILED() checks in the
D3D11VertexShader/D3D11FragmentShader constructors never fired and failed_ was
never set. Return E_FAIL instead, and only hand out the bytecode when the shader
object was actually created.
Failed() had no callers at all, so a failed shader was handed to the draw as
usual: VSSetShader(nullptr), CreateInputLayout on empty bytecode, and the
ignored HRESULT from SetupDecFmtForDraw meant IASetInputLayout(nullptr). The
draw then did nothing, with no log line to explain it. Skip the draw and warn
instead, like the GL backend does.
Previously, "Smart 2D texture filtering" was limited to through-mode
draws, but many games use fully transformed draws to do 2D elements.
An example of this is Outrun in the menus, and it's always been plagued by
horrible filtering artifacts.
With the improved Smart 2D texture filtering, the artifacts are gone!
Of course, instead of glitchy bilinear you instead get point sampled
texturing so it looks more pixellated, but no more ugly borders between letters
in the game.
