[flutter_runner] Increase Skia graphics resource cache bytes to 16mb This value started at 512mb, and was reduced to 8mb in efforts to fight OOM issues that were happening at the time. The value was not tuned w.r.t. FPS. For the image scrolling workload, just bumping it up to 16mb achieves significant "GPURasterizer::Draw" duration improvements. The full stats from the traces I took are listed below. Most importantly, the reduction is large enough that the majority of our "vsync callback" + "GPURasterizer::Draw" durations are now below the 16.67ms budget. “GPURasterizer::Draw” durations: Before (8mb) -> After (16mb) avg 12,499,036 ns -> 3,258,264 ns max 32,923,333 ns -> 11,988,792 ns min 1,083,625 ns -> 1,203,375 ns std 3,663,162 ns -> 1,339,275 ns pct_050 11,565,301 ns -> 2,631,807 ns pct_090 16,556,576 ns -> 5,488,671 ns See FL-153 for the traces. It is possible that for different workloads, a larger cache size will be required (in order to achieve 60 FPS), however for now let's try to increase it by only the necessary amount.

Topaz augments system functionality by implementing interfaces defined by underlying layers. Topaz contains four major categories of software: modules, agents, shells, and runners.
For example, modules include the dashboard, and runners include the Web, Dart, and Flutter runners.
