DrMemory doesn't seem to work with the Chromium WebGL workloads

_From [bradc...@google.com](https://code.google.com/u/110304265766688778552/) on March 15, 2012 20:31:58_

What steps will reproduce the problem? 1. Run: .\tools\valgrind\chrome_tests.bat -t chrome --tool drmemory_light --build-dir=build\Release
2. Attempt to run WebGL content from (for example) chromeexperiments.com
3. Observe that none of the WebGL content works properly What version of the product are you using? On what operating system? I tested this with a Chromium developer build @ r126517 Does the problem go away when running in light mode (pass "-light" to Dr.
Memory)? What about when running with the options "-leaks_only
-no_count_leaks -no_track_allocs"?
Nope, I've only tested in light mode so far.

Testing on a HP z600, Windows 7 64-bits.
