Wine 4.0

What's new in this version:

Direct3D:
- Initial support for Direct3D 12 is implemented. Direct3D 12 support requires the vkd3d library, and a Vulkan-capable graphics card
- The Multi-Threaded Command Stream feature is enabled by default
- OpenGL core contexts are always used by default when available. In the previous release, these were already used by default for Direct3D 10 and 11 applications on AMD and Intel graphics cards. That has been extended to all graphics cards, and all versions of Direct3D before 12

Among others, the following notable Direct3D 10 and 11 features are implemented:
- Multi-sample textures and views, as well as multi-sample resolves
- Per-sample fragment shading
- Support for 1D textures
- Draws without render target views or depth/stencil views
- Multiple viewports and scissor rectangles per draw
- Depth clipping control
- Depth bias clamping
- Stream output without geometry shaders
- Several more capability queries
- Several more resource formats
- The "depth bias clamping" feature mentioned above requires the ARB_polygon_offset_clamp/EXT_polygon_offset_clamp OpenGL extension. All Direct3D 10+ capable hardware should be able to support that extension, but it has come to our attention that some NVIDIA "Legacy Drivers" do not. We encourage affected users to explore whether the Free Software Nouveau drivers meet their needs
- Several Direct3D 11 interfaces have been updated to version 11.2, and several DXGI interfaces have been update to version 1.6. This allows applications requiring those newer interfaces to start working
- The first steps towards more fine-grained locking in the Direct3D implementation have been taken. This will be an ongoing effort to take better advantage of modern high core count CPUs
- Support for using the correct swap interval is implemented, for both DXGI and DirectDraw applications
- Application-configurable frame latency is implemented for Direct3D 9Ex and DXGI applications
- S3TC-compressed 3D textures are supported. S3TC-compressed 2D textures were already supported, provided the OpenGL drivers supported them
- When the ARB_query_buffer_object OpenGL extension is available, query results can be polled with lower latency, resulting in a modest performance improvement in specific cases
- Validation of Direct3D 8 and 9 resource pool and usage restrictions, as well as blit restrictions, has been improved
- The Direct3D graphics card database recognizes more graphics cards

New HKEY_CURRENT_USERSoftwareWineDirect3D registry keys:
- "MultisampleTextures" (REG_DWORD) Enable (0x1, default) or disable (0x0) support for multi-sample textures
- "Renderer" (REG_SZ) The backend API to target. Possible values are "gl" (default) for OpenGL and "gdi" for GDI

Deprecated HKEY_CURRENT_USERSoftwareWineDirect3D registry key:
- "DirectDrawRenderer" This has been superseded by the "Renderer" setting above

Removed HKEY_CURRENT_USERSoftwareWineDirect3D registry key:
