            Bug ID: 143528
           Summary: Pages using WebGLRenderingContext cannot go into the
                    PageCache
    Classification: Unclassified
           Product: WebKit
           Version: 528+ (Nightly build)
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Keywords: InRadar
          Severity: Normal
          Priority: P2
         Component: WebGL

Pages using WebGLRenderingContext cannot go into the PageCache because WebGLRenderingContextBase::canSuspendForPageCache() returns false.

Since we have code for handling context loss and restoring it, it seems like we should be able to force a synthetic context loss upon suspending, and try to restore it upon resuming.
