I suggest using 100 as the default value for record and rasterize repeat. 100
gives sufficiently low variance (tested on Linux; the old benchmark used 20).
1000 would be nice to have, but I'm concerned that runtimes on Android could get
very long.

Please add command line arguments --rasterize-repeat and --record-repeat to
adjust those values.

Done.
