SharedSurface_EGLImage has mostly avoided bitrotting. However, it now sometimes gets destructed after the GLContext has been lost, resulting in a crash when attempting to clean up its resources. To avoid this, we hold a weak reference to the EglDisplay, and use that to clean up rather than the GLContext. To support rendering with SWGL, EGLImageTextureHost ensures the correct preferCompositorSurface, supportsExternalCompositing, and imageType values are sent to webrender. RenderEGLImageTextureHost now implements RenderTextureHostSWGL, as well as the new CreateTextureSource() function, and EGLImageTextureSource is initialized with a GL context reference so that it may actually work. Additionally we use eglWaitSync() rather than eglClientWaitSync() where available for improved performance. And we ensure that we bind the EGL images' textures to GL_TEXTURE_2D rather than GL_TEXTURE_EXTERNAL when running on the Android emulator to work around the buggy implementation in some emulator versions.
