File third_party/WebKit/Source/platform/graphics/ImageBuffer.cpp (right):

https://codereview.chromium.org/1775613002/diff/1/third_party/WebKit/Source/p...
third_party/WebKit/Source/platform/graphics/ImageBuffer.cpp:318:
WTF::ArrayBufferContents::allocateMemoryOrNull(allocSizeInBytes,
mayHaveStrayArea ? WTF::ArrayBufferContents::ZeroInitialize :
WTF::ArrayBufferContents::DontInitialize, data);
Nit: might be clearer to pull the initialize enum (results of the ternary) out
into a temporary var.
