  Message : Add support for D3D11 texture backed EGLImages Implement EGL_ANGLE_image_d3d11_texture extension. Images created with this extension might not be renderable based on bind flags and resource usage of the client provided texture in which case attaching them to a framebuffer won't succeed. The intended use case is to bind the front and back buffers of a swap chain to GL textures that can be used for rendering in the case of the back buffer and as a shader input for the front buffer.

• ANGLE EGL Headers

  The EGL headers ANGLE uses are generated using the Khronos tools but modified to include function pointer types and function prototype guards.

  Regenerating EGL.h

  1. Install Python 3 (not 2) with the lxml addon. You can do this using pip install lxml from your Python's Scripts folder.

  2. Clone https://github.com/KhronosGroup/EGL-Registry.git.

  3. Edit EGL-Registry/api/genheaders.py:

     1. Look for the section titled # EGL API - EGL/egl.h (no function pointers, yet @@@)
     2. Change genFuncPointers = False, to genFuncPointers = True,
     3. Change protectProto = False, to protectProto = 'nonzero',
     4. Change protectProtoStr = 'EGL_EGLEXT_PROTOTYPES', to protectProtoStr = 'EGL_EGL_PROTOTYPES',

  4. Set your working directory to EGL-Registry/api/.

  5. Run python genheaders.py -registry egl.xml EGL/egl.h

  6. The generated header will now be in EGL-Registry/api/EGL/egl.h. You can copy the header over to this folder.

  7. Also update scripts/egl.xml with the latest version from EGL-Registry/api/.
