Sure, we can remove this now, but if we do there's more we want to remove at the
same time, namely the whole SkRecords::PartialDraw class in SkRecordDraw.cpp. 
It was only different fro SkRecords::Draw in clear().

 // Check that clears are converted to drawRects
 DEF_TEST(RecordDraw_PartialClear, r) {
     static const int kWidth = 10, kHeight = 10;
 
     SkRect rect = { 0, 0, kWidth, kHeight };
 
     SkRecord record;
     SkRecorder recorder(&record, kWidth, kHeight);
     recorder.clear(SK_ColorRED);
 
     SkRecord rerecord;
     SkRecorder canvas(&rerecord, kWidth, kHeight);
     SkRecordPartialDraw(record, &canvas, NULL, 0, rect, 0, 1, SkMatrix::I()); // replay just the clear
 
     REPORTER_ASSERT(r, 3 == rerecord.count());
     assert_type<SkRecords::Save>    (r, rerecord, 0);
     assert_type<SkRecords::DrawRect>(r, rerecord, 1);

     REPORTER_ASSERT(r, drawRect->rect == rect);
     REPORTER_ASSERT(r, drawRect->paint.getColor() == SK_ColorRED);
