How to publish your Fabric mod with CurseGradle

CurseGradle is a Gradle plugin that lets you publish artifacts to CurseForge. Consult the CurseGradle wiki for the full details. It works out of the box for ForgeGradle projects, but requires a bit of configuration for Fabric projects, which is the subject of this gist.

CurseGradle will assume the environment is a ForgeGradle environment, so its integration has to be manually switched off. Without ForgeGradle, CurseGradle doesn't know which Minecraft version you are working with, so it has to be specified manually. The correct main artifact is the output of the remapJar task.

OpenGL calls, OpenGL state, and state leaks

Making OpenGL calls has a performance cost. It is therefore desirable to reduce the amount of calls.

OpenGL has global state. The state is modified by enabling/disabling blending/culling/alpha testing/etc, specifying the blend function, changing the cull face, etc.

A state leak happens when a method leaves OpenGL in a different state after being called. This is generally undesirable as it often breaks expectations about the OpenGL state in other methods.

Modifying the OpenGL state requires OpenGL calls. Minecraft is not particularly optimized for reducing the amount of OpenGL calls, but makes an attempt using GlStateManager.
