This still has to work...

-        SkPaint paint;
-        paint.setFilterQuality(kMedium_SkFilterQuality);

-        context->flush();
-
-        REPORTER_ASSERT(reporter, true == tex->texturePriv().hasMipMaps());
-        REPORTER_ASSERT(reporter, false == tex->texturePriv().mipMapsAreDirty());
-
-        // Invalidating the contents of the bitmap should invalidate the mipmap, but not de-allocate
-        bitmap.notifyPixelsChanged();
-        REPORTER_ASSERT(reporter, true == tex->texturePriv().hasMipMaps());
-        REPORTER_ASSERT(reporter, true == tex->texturePriv().mipMapsAreDirty());
-
-        surface->unref();
-        texRT1->unref();
-        texRT2->unref();
-    }
