[Merge] lp:~gerboland/qtubuntu/adopt-more-eglconvenience2 into lp:qtubuntu

[Loïc Molinari]

Review: Needs Information

Couldn't we set workaround_brokenFBOReadBack right after context creation in qtubuntu? That would avoid, at each makeCurrent() call, fetching data from different places in memory (the context, the private context and the bss for platforms with non-broken FBO readback) with the potential cache misses implied.
