/**
* @fileoverview Base class for linux perf event parsers.
*
* The linux perf trace event importer depends on subclasses of
* Parser to parse event data. Each subclass corresponds
* to a group of trace events; e.g. SchedParser implements
* parsing of sched:* kernel trace events. Parser subclasses must
* call Parser.registerSubtype to arrange to be instantiated
* and their constructor must register their event handlers with the
* importer. For example,
*
* var Parser = tracing.importer.linux_perf.Parser;
*
* function WorkqueueParser(importer) {
* Parser.call(this, importer);
*
* importer.registerEventHandler('workqueue_execute_start',
* WorkqueueParser.prototype.executeStartEvent.bind(this));
* importer.registerEventHandler('workqueue_execute_end',
* WorkqueueParser.prototype.executeEndEvent.bind(this));
* }
*
* Parser.registerSubtype(WorkqueueParser);
*
* When a registered event name is found in the data stream the associated
* event handler is invoked:
*
* executeStartEvent: function(eventName, cpuNumber, ts, eventBase)
*
* If the routine returns false the caller will generate an import error
* saying there was a problem parsing it. Handlers can also emit import
* messages using this.importer.model.importWarning. If this is done in lieu of
* the generic import error it may be desirable for the handler to return
* true.
*
* Trace events generated by writing to the trace_marker file are expected
* to have a leading text marker followed by a ':'; e.g. the trace clock
* synchronization event is:
*
* tracing_mark_write: trace_event_clock_sync: parent_ts=0
*
* To register an event handler for these events, prepend the marker with
* 'tracing_mark_write:'; e.g.
*
* this.registerEventHandler('tracing_mark_write:trace_event_clock_sync',
*
* All subclasses should depend on importer.linux_perf.parser, e.g.
*
* base.defineModule('importer.linux_perf.workqueue_parser')
* .dependsOn('importer.linux_perf.parser')
* .exportsTo('tracing', function()
*
* and be listed in the dependsOn of LinuxPerfImporter. Beware that after
* adding a new subclass you must run build/generate_about_tracing_contents.py
* to regenerate about_tracing.*.

*
* A few extra things are done by this class in the name of speed:
* - Viewport culling: off-viewport rectangles are discarded.
*
* - The actual discarding operation is done in world space,
* e.g. pre-transform.
*
* - Rather than expending compute cycles trying to figure out an average
* color for fused rectangles from css strings, you instead draw using
* palletized colors. The fused rect color is choosen from the rectangle with
* the higher alpha value, if equal the max pallete index encountered.
*
