Bug ID: 253614
Summary: Use the Copy CompositeOperator when copying canvas
into its layer
Product: WebKit
Version: WebKit Nightly Build
Hardware: Unspecified
OS: Unspecified
Status: NEW
Severity: Normal
Priority: P2
Component: Layout and Rendering
Assignee: webkit-unassigned at lists.webkit.org

When the canvas buffer is the only draw into the layer, we should be able to just directly copy the pixels instead of blending. This also means we can skip clearing the back buffer.
