Do we need extra generation step? Or is setting should have mipmap to true while creating the render pass SkSurface enough?

https://cs.chromium.org/chromium/src/components/viz/service/display/skia_renderer.cc?sq=package:chromium&l=807

Looking at code, when SkSurface is created from MakeRenderTarget, the mipmap information is passed in: https://cs.chromium.org/chromium/src/components/viz/service/display/skia_renderer.cc?sq=package:chromium&l=1333

And when we use the RenderPass, we snap a SkImage, which in Skia would comply with appropriate mip map information:https://cs.chromium.org/chromium/src/third_party/skia/src/image/SkSurface_Gpu.cpp?g=0&l=107

I think I just need to remove the NOTIMPLEMENTED but say it's a noop?

Test for mipmap is the GLRendererPixelTest.TrilinearFiltering.
