[Mesa-dev] Make "Grand Ages: Medieval" playable with compat profile overrides

[Timothy Arceri]

The Game crashes on start-up if it can't create a compat 4.1 profile.

It also wants tess shaders and ARB_draw_indirect to be avaliable in
compat but they require actual work as the would be accessable to
currently supported GL versions if enabled. It seems playable 
without them.
