Shaders incompatible with FRAPI

[winkado]

Is your feature request related to a problem? Please describe.
Multiple mods make use of the Fabric Rendering API to, well, render things. An example is Baritone's pathfinding render which is completely disabled upon enabling shaders.

Describe the solution you'd like
I would like for Iris' renderer to support FRAPI so that shaders can be used in combination with FRAPI utilizing mods, such as Baritone.

Describe alternatives you've considered
I've considered using renderers such as Canvas or just sticking to Indigo. However, I feel there are no real alternatives to Iris and that it is the only good shader mod.

Additional context

Iris supports FRAPI (see Continuity and similar); this is likely an unrelated issue.
