Possibly have the array index already appended? So how do you detect
that here?
By 'possible array index' I mean that not all the XFB varyings are
arrays. Maybe better text would be just:
"Transform feedback varyings have array index already appended in
their names"
If it's not array, then of course it does not have it.
Yes, this comment makes a lot more sense. But I guess having this
distinction is the problem. How much work would XFB varyings working in
the same as any other resource when it comes to the name?
XFB resources point to 'gl_transform_feedback_varying_info' which gets
generated with names that come as user input from
glTransformFeedbackVaryings function (and should match what comes out
from glGetTransformFeedbackVarying). I don't see a straightforward way
to change this without quite a bit of changes in the XFB code so I would
like to have this distinction, it is a different sort of resource type.
