skia2/tests/PromiseImageTest.cpp
Greg Daniel fe995770fe Remove all unused uniqueKey support from SkPromiseImageTexture. 
At this point SkPromiseImageTexture is not much more than a wrapper
around a GrBackendTexture. The next steps would be to switch to just
directly using GrBackendTexture in the fulfill procs and deleting
SkPromiseImageTexture.
