include/gpu/gl/GrGLInterface.h:220: GLPtr<GrGLLoadIdentityProc> fLoadIdentity;
We now actually check for these in validate() regardless of NV_pr status so
moved them up into their rightful place from below.

We were making this a global. But when we started checking extension strings
that was no longer really correct since the strings are context-specific. This
function now always creates a new interface (or returns NULL). The factories for
other platforms should be similarly fixed.

src/gpu/gl/android/GrGLCreateNativeInterface_android.cpp:28:
interface->fActiveTexture = glActiveTexture;
The rest of this function copy/pasted from below.

src/gpu/gl/android/GrGLCreateNativeInterface_android.cpp:191:
interface->fActiveTexture = (GrGLActiveTextureProc)
eglGetProcAddress("glActiveTexture");
Here to the end was generated by regular expressions, with a few tiny tweaks:

Removed a few ES-only extension functions
Added NV suffix to path rendering function names in ""s
Put NV path rendering functions behind a check for the extension.

Maybe something like: // this is okay b.c. the only Android driver we expect to
support desktop GL is from nVidia and is v4.4
