           Summary: WebGL allows use of CanvasObjects on multiple contexts
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: PC
        OS/Version: Mac OS X 10.5
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: HTML DOM
        AssignedTo: webkit-unassigned at lists.webkit.org

if i create two contexts, and bind programs to each of them, then it becomes
possible for me to use CanvasObjects from each of them on the other.

This is not any kind of security or whatever problem -- the issue would appear
that it is simply the underlying GL identifier being passed unchecked to the
context which just ends up referencing that contexts equivalent resource.
