Step 2 of #8, into the stonecutter integration branch. 1.21.10 now builds from src/ as :1.21.10, and versions/1.21.10/src is gone.

Version comments (API differences)

File	1.21.10	1.21.11
`ShaderUtils`	`RenderLayer.of(…, MultiPhaseParameters)`, `RenderLayer.getEntityAlpha`	`RenderSetup`, `RenderLayers.entityAlpha`
`CameraMixin`	`Camera.update(BlockView, …)`	`Camera.update(World, …)`
`RenderScopeImpl`	text render state without the extra flag, `TextureSetup.withoutGlTexture`	extra flag, `TextureSetup.of(view, sampler)`
`SplashOverlayMixin`	`Screen.init(client, w, h)`	`Screen.init(w, h)`
`SaturnRenderState`	no jspecify	`@NonNull`

Logic: nothing lost, one fix

Features 1.21.11 leaves out stay on 1.21.10. Each has a TODO on the 1.21.11 side:
- WorldFeatureImpl.getWorldAge (returns 0 on 1.21.11)
- SaturnScreenFabric.resize (not hooked on 1.21.11)
- EntityDrawerImpl clearing the hitbox
Hats now render on 1.21.10.
- Before: its HatFeatureRenderer overrode the render-queue render(…) with an empty body, and the working code sat in an old VertexConsumerProvider method that nothing called.
- Now: 1.21.10 uses 1.21.11's render-queue implementation (HatFeatureRenderer, ObjModel, ObjRenderer), which compiles unchanged on 1.21.10.
1.21.10 also gets 1.21.11's null check on the player's display name in PlayerEntityRendererMixin.

Checks

1.21.10 jar vs the old :mc-1.21.10 jar: same 415 entries, identical fabric.mod.json and mixin configs. Comparing bytecode (ignoring line numbers), only these classes differ: the three hat classes, PlayerEntityRendererMixin (the null check) and ShaderUtils (a new entityAlpha helper). Everything else compiles to the same bytecode.
1.21.11 jar: only ShaderUtils differs (the same helper).
Switching versions: Set active project to 1.21.10 compiles, and Reset active project leaves src/ unchanged. The version comments are already in Stonecutter's own layout.
Builds: a cold buildAll --no-build-cache builds all 8 jars in 85 s, and compileJava passes.
In game: :1.21.10:runClient starts. Only 1.21.11's run folder has DevAuth, so the 1.21.10 dev client plays offline and can't log in to the Saturn server.

Needs an in-game check: hats on 1.21.10, with a logged-in account that owns one.

Step 2 of #8, into the `stonecutter` integration branch. 1.21.10 now builds from `src/` as `:1.21.10`, and `versions/1.21.10/src` is gone. ## Version comments (API differences) | File | 1.21.10 | 1.21.11 | |---|---|---| | `ShaderUtils` | `RenderLayer.of(…, MultiPhaseParameters)`, `RenderLayer.getEntityAlpha` | `RenderSetup`, `RenderLayers.entityAlpha` | | `CameraMixin` | `Camera.update(BlockView, …)` | `Camera.update(World, …)` | | `RenderScopeImpl` | text render state without the extra flag, `TextureSetup.withoutGlTexture` | extra flag, `TextureSetup.of(view, sampler)` | | `SplashOverlayMixin` | `Screen.init(client, w, h)` | `Screen.init(w, h)` | | `SaturnRenderState` | no jspecify | `@NonNull` | ## Logic: nothing lost, one fix - **Features 1.21.11 leaves out stay on 1.21.10.** Each has a `TODO` on the 1.21.11 side: - `WorldFeatureImpl.getWorldAge` (returns 0 on 1.21.11) - `SaturnScreenFabric.resize` (not hooked on 1.21.11) - `EntityDrawerImpl` clearing the hitbox - **Hats now render on 1.21.10.** - Before: its `HatFeatureRenderer` overrode the render-queue `render(…)` with an empty body, and the working code sat in an old `VertexConsumerProvider` method that nothing called. - Now: 1.21.10 uses 1.21.11's render-queue implementation (`HatFeatureRenderer`, `ObjModel`, `ObjRenderer`), which compiles unchanged on 1.21.10. - **1.21.10 also gets 1.21.11's null check** on the player's display name in `PlayerEntityRendererMixin`. ## Checks - **1.21.10 jar vs the old `:mc-1.21.10` jar:** same 415 entries, identical `fabric.mod.json` and mixin configs.

Step 2 of #8. versions/1.21.10/src is gone; 1.21.10 builds from src/ as
:1.21.10, with versions/1.21.10 keeping only gradle.properties and run/.

API differences go behind version comments: render layers (ShaderUtils),
Camera.update's World vs BlockView (CameraMixin), the text and textured-quad
render states (RenderScopeImpl), Screen.init (SplashOverlayMixin) and
jspecify's @NonNull (SaturnRenderState).

Features 1.21.11 leaves out stay on 1.21.10, with a TODO for 1.21.11:
WorldFeatureImpl.getWorldAge, SaturnScreenFabric.resize and
EntityDrawerImpl clearing the hitbox.

Hats now render on 1.21.10: its HatFeatureRenderer overrode the
render-queue method with an empty body, and the working code sat in an old
VertexConsumerProvider method nothing called. 1.21.10 now uses 1.21.11's
render-queue implementation (HatFeatureRenderer, ObjModel, ObjRenderer),
and also gets 1.21.11's null check on the player's display name.

The 1.21.10 jar has the same entries, fabric.mod.json and mixin configs as
before; only those four classes and ShaderUtils (a helper method for
entityAlpha) have different bytecode. The 1.21.11 jar only differs in
ShaderUtils.
