Reduce opList splitting by default in Skia Local Skia and DDL recording will always attempt to reduce opList splitting. Android, Flutter, Google3 and non-DDL Chrome will not. Note that this is a bit aggressive. Intermediate flushes based on memory usage have not yet been implemented. The plan is to run this locally in Skia until the next Chrome branch and then enable it everywhere else (when intermediate flushes have been implemented). OpList splitting reduction in Chrome is disabled in the following Chrome-side CL: https://chromium-review.googlesource.com/c/chromium/src/+/1588756/ (Disable opList splitting reduction in Skia) It is disabled in Android in: https://googleplex-android-review.git.corp.google.com/c/platform/external/skia/+/7259923 (Update #defines to suppress Ganesh features in SkUserConfigManual.h) It is disabled in Flutter and Google3 w/in this CL.

# Fast low-precision software rendering isn't a priority for Flutter.
disable legacy shaders in flutter All of Flutter's non-test drawing is done with Ganesh, and the few shaders that are legacy-only are not used by Flutter. This should cut a bunch of essentially-dead code from Flutter, though some of the Flutter test images may change because those test images are software rasterized. Hopefully nothing should look terribly different. Looks like this cuts ~27K from Flutter.

"SK_DISABLE_LOWP_RASTER_PIPELINE",
cut out the rest of blend modes in flutter SkXfermode_opts.h is moot when SK_FORCE_RASTER_PIPELINE_BLITTER is defined. There are a couple other blitters and routines and things that are also just there for 565/8888 performance, so I think we can just turn on SK_FORCE_RASTER_PIPELINE_BLITTER and start guarding the rest of them similarly. Looks like maybe cuts another 13K?
