            Bug ID: 211156
           Summary: [WebGL2] Implement multiple render target entry points
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebGL
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: kbr at google.com
                CC: dino at apple.com, jdarpinian at chromium.org
        Depends on: 210994, 126994
            Blocks: 126404

In Bug 126994 support was supposedly added for multiple render targets, including the following entry points:

drawBuffers
clearBufferfv
clearBufferiv
clearBufferuiv
clearBufferfi

but the implementations were no-op'ed. This leads to at least one conformance test failure.

It's not clear to me how many layout tests' results will be changed as a result of fixing this, so splitting it off from other bugs.
