GrGLMakeNativeInterface()

sk_sp< const GrGLInterface > GrGLMakeNativeInterface

(

)

Rather than depend on platform-specific GL headers and libraries, we require the client to provide a struct of GL function pointers. This struct can be specified per-GrContext as a parameter to GrContext::MakeGL. If no interface is passed to MakeGL then a default GL interface is created using GrGLMakeNativeInterface(). If this returns nullptr then GrContext::MakeGL() will fail.

The implementation of GrGLMakeNativeInterface is platform-specific. Several implementations have been provided (for GLX, WGL, EGL, etc), along with an implementation that simply returns nullptr. Clients should select the most appropriate one to build.
