Created my own flag parser, based off of gflags. Share common code between bench_ and render_ to set up the PictureRenderer. Fix an include error in SkPictureRenderer.h. Simplified parameter passing in render_pictures_main. Switch to using an SkAutoTUnref for the PictureRenderer. I also changed the input format somewhat, so the buildbots need to be updated as well: https://codereview.appspot.com/7441044/ Fixed a bug in PictureBenchmark where calling setTimeIndividualTiles(false) sets the member variable to true. Removed setDeviceType from PictureBenchmark, since only the PictureRenderer needs to know which device type to use. Some changes to the input format: '--logPerIter' no longer takes a 1 or 0. Instead, '--logPerIter' turns it on and '--nologPerIter' turns it off (with off as the default). (Note that this is for bench_pictures; bench still uses the old format) Change '--device' to '--config' and 'bitmap' to '8888' to be the same as gm. Requires '--r' before inputs (to match gm), though there can be multiple inputs following it. Changed --enable-deferred-image-decoding (which no one uses but me yet anyway) to --deferImageDecoding, since the former is incompatible with the flag parser. Changes to behavior: Show a short error message on failure (rather than the explanation of all flags).

// 1) longRunningTimer, along with perTileTimerData, will time how long it takes to draw
// one tile fRepeats times, and take the average. As such, it will not respect the
// logPerIter or printMin options, since it does not know the time per iteration. It
// will also be unable to call flush() for each tile.
// The goal of this timer is to make up for a system timer that is not precise enough to
// measure the small amount of time it takes to draw one tile once.
//
// 2) perTileTimer, along with perTileTimerData, will record each run separately, and
// then take the average. As such, it supports logPerIter and printMin options.
//
// Although "legal", having two gpu timers running at the same time
// seems to cause problems (i.e., INVALID_OPERATIONs) on several
// platforms. To work around this, we disable the gpu timer on the
// long running timer.
