GLProfile's mapping code does not consider the following combination:
- GL4 software
- GL3 hardware
and hence maps GL4-software -> [GL2ES2, GL2GL3],
where GL3-hardware -> [GL2ES2, GL2GL3] is desired.
This combination has recently been observed on
Mac OSX 10.9.5, which includes a software GL 4.1 implementation.
However, other systems could be affected as well.
Only use the higher profile, if hardware-accelerated or none of the
lower profiles offers hardware-acceleration!
This extra condition was missing for certain profiles,
e.g. GL4, GL4bc, GL3, GL3bc and GL2.
