Revert 261543 "cc: Add picture recording modes for benchmarking"
> cc: Add picture recording modes for benchmarking
>
> This patch adds three different picture recording modes for benchmarking
> purposes:
>
> 1. RECORD_NORMALLY. This is the default and produces a normal recording
> as before.
>
> 2. RECORD_WITH_NULL_CANVAS. This mode uses SkNullCanvas to avoid (most
> of) the Skia processing that happen during recording. Can be used to
> estimate the recording workload inside Blink.
>
> 3. RECORD_WITH_PAINTING_DISABLED. Passes a NULL canvas to Blink, which
> causes the GraphicsContext object to disable painting. This mode
> gives an estimate of the recording workload of Blink excluding the
> processing inside GraphicsContext.
>
> This patch also modifies the rasterize_and_record_micro benchmark to
> report the recording time for each mode (record_time_ms,
> record_time_null_canvas_ms and record_time_painting_disabled_ms
> respectively).
>
> Anecdotally on a z600 and the key_silk_cases page set, SkNullCanvas cuts
> recording time to 50% and disabling painting down to 19%.
