/**
 * This class is used to support ATrace in android apps. It hooks into the SkEventTracer system. It
 * currently supports the macros TRACE_EVENT*, TRACE_EVENT_INSTANT*, and TRACE_EVENT_BEGIN/END*.
 * For versions of these calls that take additoinal args and value pairs we currently just drop them
 * and report only the name. Since ATrace is a simple push and pop system (all traces are fully
 * nested), if using BEGIN and END you should also make sure your calls are properly nested (i.e. if
 * startA is before startB, then endB is before endA).
