[lazarus] opengl as requirement

[Marco van de Voort]

I'm creating a small lazarus distro for a friend, and came upon a problem.

FPC 1.0.10 for FreeBSD has a small glitch in the Opengl unit, which is
simple to fix, but annoying for end users to deal with. (need to post edit
link.res)

However I'm wondering what the Opengl unit is exactly needed for.

Do components use it, or is it only a Lazarus IDE requirement?
