Make all SkImages mipmapped w/in the DDL testing harness
When timing DDL performance with SKPs, if the mipmapping requirements of a given SkImage are gotten wrong at record time, the mipmaps will keep getting regenerated over and over again. This CL works around the problem by just creating all promise images as mipmapped. A better (but longer term solution) would be to examine the actual draw ops w/in an SKP.
Even more aggressively, we may want to disable mipmap regeneration w/in DDLs.
For desk_nytimes.skp on Windows/gl we have:
before CL after CL
w/ DDLs 7.999 3.136
w/o DDLs 1.953 1.863
This perf improvement won't be seen by Chrome since, presumably, they're creating their backend textures w/ the correct mipmappedness. Additionally, they, hopefully, aren't recording the same DDL over and over again (with incorrect mipmappedness).
