This leads me to similar questions about the rest of these. They use osmesa
because they are creating some compositor output, so they already depend on cc.

For components_tests, the content_shell_and_tests.gyp depends on
cc_test_support:
https://code.google.com/p/chromium/codesearch#chromium/src/content/content_te...

At least one other (chrome_tests_unit) also does this. But how come that dep in
cc_test_support isn't enough elsewhere too?
