--- Comment #4 from Grazvydas Ignotas notasas@gmail.com --- It indeed does, thanks again.
It would be nice to propose a GL_MESA_ extension for this, looks like most work would be writing the .spec file as the implementation would be trivial? I guess you could do it better but I could give that a try someday if you don't want to. This is of course only if the wine project isn't against using such MESA extension.
