Subject: egl: Mention if swrast is being forced

egl: Mention if swrast is being forced

The system can be disabling HW acceleration unbeknown to the user,
leading to a long debug session trying to work out which component is
failing. A quick mention that it is the environment override would be
very useful.

v2: Use more generic "CPU renderer" and so try to avoid jargon.
