[PATCH 0/1] MR4365: opengl32: Skip filter_extensions_index() on GL contexts < 3.0.

[Matteo Bruni (＠Mystral)]

glGetStringi() is not available before 3.0. We can't trust its
function pointer being NULL since the GL implementation is allowed to
return anything in this case (*cough* macOS's GL on Metal *cough*).

This probably regressed when fd92954df8cf12c61e08c7ef7acf172efb7c44ad
removed the "if (!disabled[0]) return FALSE;" exit from
filter_extensions(), although that simply exposed an existing issue.
