Summary
[Chromium] context-creation-and-destruction layout tests are slow

These tests are slow (landed as part of
r123556
, I guess): fast/canvas/webgl/context-creation-and-destruction.html = PASS platform/chromium/virtual/gpu/fast/canvas/webgl/context-creation-and-destruction.html = PASS
http://test-results.appspot.com/dashboards/flakiness_dashboard.html#tests=fast%2Fcanvas%2Fwebgl%2Fcontext-creation-and-destruction.html
I've marked them SLOW in TestExpectations

These are starting to fail sometimes, so I have updated TestExpectations accordingly:

This test is now consistently timing out, even marked as "Slow".

I'm going to remove this test. It was added for
Bug 76255
but the "fix" for that bug (which is still evolving in
Bug 104733
) wasn't actually tested by this test.

The point of this test is for a hypothetical site similar to docs.google.com. Imagine a sight that makes graphs from spreadsheets. For certain effects they create a WebGL context, render a graph, make an image, then kill the WebGL context (ie, let it go) Such a site shouldn't stop working after a certain number of context create-use-destroy cycles.

The test can be added again once there is code in WebKit supporting it. Right now WebKit imposes no limit on the number of WebGL contexts that can be allocated nor on the amount of memory that can be allocated by all WebGL contexts. Having either of those two limits in place would let the test in the Khronos repository run successfully and then we could re-introduce a stripped down version as a layout test. It is a little distressing though that not even 8 iterations of the test can run within the timeout.
