Migrate from GLEW to libepoxy or GLAD

[cryptomilk]

Feature description

Hi,

we are currently trying to get rid of GLEW in Fedora as it isn't maintained anymore. Also GLEW with the last release only supports GLX and not EGL.

There are two ways moving forward:

• Use libepoxy
• Use GLAD, or check out the webservice for glad2 to generate the files you need!

With both of them migration should be straight forward.

Thanks for considering!

Hi @cryptomilk ... I see you went around the netz with this call :)

Realistically, our timeline for this would be 6 months, to go into our next release 6.38, 6.36 was just released and the release cadence is twice a year.

This probably means we'll miss 43 and could have it in time to enter 44. Does this work?

That's totally fine. The migration work isn't much for both.

Yep, went through the whole Fedora list ;-)

We also have patch releases which are done several times per year. For us Fedora is an important platform and I would be ready, if needed, to provide a ROOT version for it in a patch release to have it working in 43.
