// AXTreeDistiller
//
//  A class that distills an AXTreeUpdate. The main API is
//  AXTreeDistiller::Distill(), which kicks off the distillation. Once a
//  distilled AXTree is ready, calls a callback.
//  When |IsReadAnythingWithScreen2xEnabled()|, the distillation is performed
//  by the Screen2x ML model in the utility process. Otherwise, distillation is
//  done using rules defined in this file.
