Clear 'm_size' of DrawingBuffer in the 'clear' function
​https://bugs.webkit.org/show_bug.cgi?id=76239

Patch by Yongsheng Zhu <​yongsheng.zhu@intel.com> on 2012-01-17
Reviewed by Kenneth Russell.

Clear the resources of DrawingBuffer but don't clear 'm_size'. This makes
's_currentResourceUsePixels' is not calculated correctly.
