I found why EGL was not working -- it should be --use-gl=egl and not
--user-gl=egl...

If one does

  $ ./apitrace trace  --api egl chromium --temp-profile --user-gl=egl
--ignore-gpu-blacklist
http://webglsamples.googlecode.com/hg/field/field.html

Chrome will use EGL. However there was a bunch of issues in apitrace:
- there was no support for intercepting dlopen(libEGL) and friends
- there was no support for retracing EGL pbuffers

Everything is now fixed, so all should work fine.
