[ADR] Geometry Shaders

[lithiumtoast]

This issue is for discussion about the architectural decision (AD) for the support of geometry shaders. Geometry shaders are considered an architecture significant requirement (ASR). The decision is recorded as an architecture decision record (ADR) in the form of a Markdown file (.md). The ADR is part of the Git repository and can be found here in the architecture decision log (ADL).

Comment in this issue if you would like to participate in the discussion of supporting geometry shaders, but do please read the ADR before commenting.
