Description Sven Gothel 2014-10-01 22:26:21 CEST
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.

Commit c85e0566c55cdc99668dd373e6b6b8b66a557c8e:

Fix GLProfile.computeProfileImpl(..):

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.
