Hi Phil,

Thanks for the review.

In this case the decision to leave the workarround in forever is easy
- it only causes minimal protocol overhead for larger strings (0.05
extra bytes per 253 characters).
In other areas an API to detect the driver / xorg and library versions
would have saved a lot of headache.

However with wayland/mir/... on the horizon, there is still hope for
better opengl drivers in mid-term future :)

Thanks, Clemens
