sc: bone eater preliminary support (#895 )

## Link to GitHub Issue or related Pull Request, if one exists Fixes #114 ## Description of change Initial support for Silent Scope: Bone Eater, enough to be playable; doesn't include QoS work needed to make this a smoother experience. * Game detection * Fix DX11 overlay to work with non-Unity games * Implements sub monitor i/o (only really needed to get past I/O check) * Try to make the game reasonably playable with a mouse * Ignore the game's attempt to move windows, position them in a reasonable place * Fix language hook ## Testing

+## Video Stream
+
+Separate from the JSON API, spice can serve the mirrored screen as a video
+stream over plain HTTP. Enable it with `-apistream`. It listens on the API port
+plus two, in the same way the WebSocket server uses the API port plus one, so
+`-api 1337` puts the stream on 1339. This means `-api` has to be enabled too.
+
+Rather than working the port out, clients should ask the JSON API for it with
+`capture.get_streams()`, which also reports which of the formats below this
+build serves, the size of each screen and whether one is already taken.
+
+Two formats are served:
+
+    http://host:1339/stream.mjpg    JPEG frames, multipart/x-mixed-replace
+    http://host:1339/stream.h264    H.264 annex-b, no container
+
+All accept the same optional query parameters:
+
+- `screen` - which screen to mirror, 0-3. Defaults to the subscreen when the
+  game has one, otherwise the main screen.
+- `fps` - frames per second, 1-60. Default 30.
+- `q` - quality, 1-100. Default 70. This is the JPEG quality for `stream.mjpg`
+  and is mapped onto the H.264 rate factor for `stream.h264`, so the same number
+  does not mean the same thing for both.
+
+For example:
+
+    http://host:1339/stream.h264?screen=1&fps=30&q=70
+
+See the wiki for format tradeoffs, latency tuning, testing commands and client
+notes.
+
+The stream is view only. Touch and other input still go through the JSON API,
+so a companion app needs both. There is no authentication on the stream port -
+anyone who can reach it can watch the screen.
+
+WinXP builds have no video stream. Neither encoder is compiled in, so nothing
+listens on the stream port even with `-apistream`, `capture.get_streams()`
+returns no data, and the JSON API's JPEG screen capture is unavailable for the
+same reason.
+
 ## Native wrapper libraries
 Spicetools provides wrapper libraries in: Arduino, C++, Dart, and Python.
 Python is the only one that is fully spec compliant.
 Other libraries may be missing features and contain bugs; please feel free to
 contribute code to fill the gaps if you work on a project using these libraries.

+## Spice SDK (for DLL hooks / plugins)
+
+As an alternative to Spice API, Spice SDK is available.
+
+This is a flat C, header-only library that can be included in your DLL. Once
+initialized, you can call directly into helper routines provided by Spicetools
+executable, making low-latency and high-throughput interactions possible.
+
+Check the documentation on the wiki for more details.

+// dear imgui: Renderer Backend for DirectX11
+// This needs to be used along with a Platform Backend (e.g. Win32)
+
+// Implemented features:
+//  [X] Renderer: User texture binding. Use 'ID3D11ShaderResourceView*' as texture identifier. Read the FAQ about ImTextureID/ImTextureRef!
+//  [X] Renderer: Large meshes support (64k+ vertices) even with 16-bit indices (ImGuiBackendFlags_RendererHasVtxOffset).
+//  [X] Renderer: Texture updates support for dynamic font atlas (ImGuiBackendFlags_RendererHasTextures).
+//  [X] Renderer: Expose selected render state for draw callbacks to use. Access in '(ImGui_ImplXXXX_RenderState*)GetPlatformIO().Renderer_RenderState'.
+//  [X] Renderer: Multi-viewport support (multiple windows). Enable with 'io.ConfigFlags |= ImGuiConfigFlags_ViewportsEnable'.
+
+// You can use unmodified imgui_impl_* files in your project. See examples/ folder for examples of using this.
+// Prefer including the entire imgui/ repository into your project (either as a copy or as a submodule), and only build the backends you need.
+// Learn about Dear ImGui:
+// - FAQ                  https://dearimgui.com/faq
+// - Getting Started      https://dearimgui.com/getting-started
+// - Documentation        https://dearimgui.com/docs (same as your local docs/ folder).
+// - Introduction, links and more at the top of imgui.cpp
+
+// CHANGELOG
+// (minor and older changes stripped away, please see git history for details)
+//  2026-XX-XX: Platform: Added support for multiple windows via the ImGuiPlatformIO interface.
+//  2026-04-23: DirectX11: Added support for standard draw callbacks (in platform_io): DrawCallback_ResetRenderState, DrawCallback_SetSamplerLinear, DrawCallback_SetSamplerNearest. Obsoleting samplers from ImGui_ImplDX11_RenderState. (#9378)
+//  2026-01-19: DirectX11: Added 'SamplerNearest' in ImGui_ImplDX11_RenderState. Renamed 'SamplerDefault' to 'SamplerLinear'.
+//  2025-09-18: Call platform_io.ClearRendererHandlers() on shutdown.
+//  2025-06-11: DirectX11: Added support for ImGuiBackendFlags_RendererHasTextures, for dynamic font atlas.
+//  2025-05-07: DirectX11: Honor draw_data->FramebufferScale to allow for custom backends and experiment using it (consistently with other renderer backends, even though in normal condition it is not set under Windows).
+//  2025-02-24: [Docking] Added undocumented ImGui_ImplDX11_SetSwapChainDescs() to configure swap chain creation for secondary viewports.
+//  2025-01-06: DirectX11: Expose VertexConstantBuffer in ImGui_ImplDX11_RenderState. Reset projection matrix in ImDrawCallback_ResetRenderState handler.
+//  2024-10-07: DirectX11: Changed default texture sampler to Clamp instead of Repeat/Wrap.
+//  2024-10-07: DirectX11: Expose selected render state in ImGui_ImplDX11_RenderState, which you can access in 'void* platform_io.Renderer_RenderState' during draw callbacks.
+//  2022-10-11: Using 'nullptr' instead of 'NULL' as per our switch to C++11.
+//  2021-06-29: Reorganized backend to pull data from a single structure to facilitate usage with multiple-contexts (all g_XXXX access changed to bd->XXXX).
+//  2021-05-19: DirectX11: Replaced direct access to ImDrawCmd::TextureId with a call to ImDrawCmd::GetTexID(). (will become a requirement)
+//  2021-02-18: DirectX11: Change blending equation to preserve alpha in output buffer.
+//  2019-08-01: DirectX11: Fixed code querying the Geometry Shader state (would generally error with Debug layer enabled).
+//  2019-07-21: DirectX11: Backup, clear and restore Geometry Shader is any is bound when calling ImGui_ImplDX11_RenderDrawData. Clearing Hull/Domain/Compute shaders without backup/restore.
+//  2019-05-29: DirectX11: Added support for large mesh (64K+ vertices), enable ImGuiBackendFlags_RendererHasVtxOffset flag.
+//  2019-04-30: DirectX11: Added support for special ImDrawCallback_ResetRenderState callback to reset render state.
+//  2018-12-03: Misc: Added #pragma comment statement to automatically link with d3dcompiler.lib when using D3DCompile().
+//  2018-11-30: Misc: Setting up io.BackendRendererName so it can be displayed in the About Window.
+//  2018-08-01: DirectX11: Querying for IDXGIFactory instead of IDXGIFactory1 to increase compatibility.
+//  2018-07-13: DirectX11: Fixed unreleased resources in Init and Shutdown functions.
+//  2018-06-08: Misc: Extracted imgui_impl_dx11.cpp/.h away from the old combined DX11+Win32 example.
+//  2018-06-08: DirectX11: Use draw_data->DisplayPos and draw_data->DisplaySize to setup projection matrix and clipping rectangle.
+//  2018-02-16: Misc: Obsoleted the io.RenderDrawListsFn callback and exposed ImGui_ImplDX11_RenderDrawData() in the .h file so you can call it yourself.
+//  2018-02-06: Misc: Removed call to ImGui::Shutdown() which is not available from 1.60 WIP, user needs to call CreateContext/DestroyContext themselves.
+//  2016-05-07: DirectX11: Disabling depth-write.
