Adds 26.3 as a Stonecutter version, the last step of #39.
Input: 26.3 replaces GLFW with SDL, which numbers keys (scancodes),
modifiers and mouse buttons differently. Saturn keeps GLFW's numbers,
which common uses and the config's keybinds store, so saved keybinds
stay valid. The new Keys class converts at the boundary: key events,
modifiers and mouse buttons coming into Saturn's screens, and key codes
going to InputConstants. Its table pairs GLFW's codes with 26.3's
InputConstants of the same name. Key names come from the game on 26.3,
and version-specific code uses InputConstants' key constants rather
than GLFW's.
Rendering: Blaze3D's API moved to renderpearl, which Stonecutter
replacements cover. PoseStack's quaternion mulPose became rotate, and
TextureTarget takes a depth format instead of a flag. 26.3 compiles
shaders through SPIR-V and reorders the transforms block, so glass.fsh
takes explicit locations and the new order behind defines that
GlassRenderer sets, and the unlit cosmetics pipeline declares its
color target, which 26.3 requires.
OptionsScreen no longer takes whether a world is open.

Adds 26.2 as a Stonecutter version (#39).
26.2 splits the HUD out of Gui into Hud and moves the open screen, the
overlay and the toasts from Minecraft to Gui. A new Screens helper gets
and sets the screen and clears the overlay on every version, and
MinecraftClientMixin opens screens through it instead of shadowing
Minecraft.setScreen. SetScreenMixin targets Gui.setScreen and the HUD
hook Hud.extractChat on 26.2.
26.2's rendering API declares samplers through bind group layouts and
gives render targets a GpuFormat, so the glass pipeline adds SAMPLER1's
layout and its backdrops are RGBA8_UNORM like vanilla's targets. The
main render target is the game renderer's, the panorama no longer takes
a fade flag, and toasts are added with SystemToast.add.

Adds 26.1 as a Stonecutter version (step 3 of #39). Its jar also
loads on the 26.1.1 and 26.1.2 hotfixes.
Most of 26.1's changes are renames: the GUI's render methods became
extract methods and GuiGraphics became GuiGraphicsExtractor, which
Stonecutter replacements cover along with the moved render state
package and GuiRenderState's add methods. The rest are version
comments:
- The menu panorama is drawn by GuiRenderer from vanilla's cube map;
the new GuiRendererMixin swaps in Saturn's while a Saturn screen is
open (empty on older versions).
- The camera works out the FOV and aligns with its entity in
alignWithEntity, so the zoom and freelook hooks move to CameraMixin.
- Gamma and the menu blur are read while extracting render state.
- The glass blur's post chain takes a Projection and its buffer.
- The dragon's alpha render type is gone; capes use entityCutout.
- Fabric API renamed KeyBindingHelper to KeyMappingHelper.
The docs describe the 26.x build and Java 25.

Step 6 of #8. versions/1.21.4/src is gone, so all eight versions (1.21.4 to
1.21.11) build from src/.
1.21.4's differences from 1.21.5 are behind version comments:
- The end gateway render layer has no render pipeline before 1.21.5
(ShaderUtils: the pipeline field only exists from 1.21.5, and the layer
is a four-way chain).
- Hat head rotation, the NativeImageBackedTexture constructor, armor slots
(inventory.armor vs getEquippedStack), MatrixStackMixin's Quaternionf,
and inside the pre-1.21.6 implementations: prevHeadYaw, GUI lighting,
ModelTransformationMode, item depth, setShaderTexture and the blur
uniform call. Those are one-line version comments, since the pre-1.21.6
blocks are already inside /* */ on newer versions.
1.21.5's drawItem wrapped its body in a second isEmpty check after already
returning early for empty stacks; the redundant check is gone, so 1.21.4
and 1.21.5 share the body.
Freelook's zoom-out (FreelookMod.shouldZoomOut in GameRendererMixin) only
existed on 1.21.4. It doesn't depend on the Minecraft version, so it's
back on every version.
With no old copies left, the mc-<v> fallback in settings.gradle.kts and
scripts/port.sh are removed, and README and VERSION_GUIDE describe the
single layout.

1.21.6's copy only differed from 1.21.7's in RenderScopeImpl: item
rendering uses ItemRenderState, which 1.21.7 renamed to
KeyedItemRenderState. That's behind a version comment; 1.21.6 keeps its
older loader_version (0.18.5) in its gradle.properties.
Moving a version over leaves the old mc-<v> project's compiled classes in
the shared build/ folder, so a removed class (1.21.6's dead NameTagMixin)
still got packaged until a clean. VERSION_GUIDE now says to run
:<v>:clean once after moving a version.

Step 5 of #8. versions/1.21.7/src is gone; 1.21.7 builds from src/ as
:1.21.7.
1.21.7's copy differed from 1.21.8's in the player render state: Fabric
API's RenderStateDataKey only exists from 1.21.8 (fabric-rendering-v1
12.6.0), so 1.21.7 had no updateRenderState hook, no SaturnRenderState,
and looked players up by name for the cloak and hat. That stays the case:
- The cloak and hat use getData on >=1.21.8 and SaturnPlayer.get(name)
before that.
- PlayerEntityRendererMixin's updateRenderState exists only on >=1.21.8,
as flat ranges (>=1.21.9, else if >=1.21.8) calling a shared
saturn$applyPlayer helper, instead of nested version blocks.
- SaturnRenderState's key only exists on >=1.21.8; the class is empty
before.
- TODO: 1.21.6 and 1.21.7 still don't show the role icon in names.
1.21.7's NameTagMixin isn't carried over: it wasn't registered in any
mixin config, so it never ran.
The 1.21.7 jar differs from the old one only as 1.21.8's did in step 4
(entityAlpha and drawGroup helpers, getIconId, and the cloak getting its
buffer at the draw call), plus the empty SaturnRenderState and the
missing dead NameTagMixin. 1.21.8-1.21.11 only differ in
PlayerEntityRendererMixin (the helper).

Step 4 of #8, the first version before the 1.21.9 render queue.
versions/1.21.8/src is gone; 1.21.8 builds from src/ as :1.21.8.
API differences behind version comments (<1.21.9 / >=1.21.9):
- Player cosmetics: FeatureRenderer.render takes a VertexConsumerProvider
instead of the render queue. The cloak, hat and OBJ renderers name the
render target "output" in both, so only the parameter type and the final
draw call differ; the OBJ face loop moved into drawGroup.
- PlayerEntityRenderer.updateRenderState's entity type, the cape texture
accessor, GameProfile getName()/getId() vs name()/id(), fonts in
TextMixin, EntityRenderDispatcher vs EntityRenderManager, Screen input
events (Click/KeyInput), and KeyBinding categories and isKeyPressed.
Features 1.21.9+ lacks stay on 1.21.8, with a TODO for 1.21.9+:
- NametagsMixin moves into src/. It hooks renderLabelIfPresent with a
VertexConsumerProvider, which 1.21.9 changed, so on 1.21.9+ its body is
empty; it stays registered, so features.mixins.json is the same for
every version.
- The splash screen's loading-bar border, and the real drag deltas in
SaturnScreenFabric.mouseDragged.
- Status effect icons keep 1.21.8's GUI atlas sprite; 1.21.9+ draws the
texture instead (getIconId), as before.
Behaviour changes on 1.21.8: the cloak and hat read the Saturn player from
the render state (set by PlayerEntityRendererMixin, by UUID) instead of
looking it up by name, and the display-name null check applies.
Co-Authored-By: Claude Opus 5.5 <[email protected]>
Step 3 of #8. 1.21.9's copy was identical to the old 1.21.10 one, so the
existing version comments already cover it and no code changes: 1.21.9 is
added to stonecutterVersions and versions/1.21.9/src is removed.
Like 1.21.10 in step 2, 1.21.9 now renders hats (1.21.11's render-queue
implementation) and gets the display-name null check. The jar has the same
entries, fabric.mod.json and mixin configs as before; only those classes
and ShaderUtils's entityAlpha helper differ in bytecode.

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.
Co-Authored-By: Claude Opus 5.5 <[email protected]>
Step 1 of #8. 1.21.11's version-specific code moves from versions/1.21.11/src
to the top-level src/, built by Stonecutter as the project :1.21.11. The other
versions still build from their own copies as :mc-<v> until they're folded in.
- settings.gradle: applies Stonecutter (Groovy controller) with
stonecutterVersions = ["1.21.11"] and skips those folders when including
the old mc-<v> projects.
- The old root build.gradle becomes stonecutter.gradle (the root project's
script, with the shared repositories, common wiring and buildAll), and
1.21.11's build.gradle becomes the root build.gradle that Stonecutter runs
for each version. versions/1.21.11 keeps its gradle.properties and run/.
- The jar has the same 415 entries, fabric.mod.json and mixin configs as
before; the only class differences also appear when rebuilding an
untouched version today.
- scripts/port.sh treats src/ as the active Stonecutter version, so changes
port between it and the old copies both ways.
- README and VERSION_GUIDE describe the layout, version comments and how to
add a version.

- Reference logo.png from the repo instead of the dead raw.github URL
(the logo lives in the common submodule, which Gitea can't serve from
a relative path, so a copy sits next to screenshot.png)
- Drop the section emojis and horizontal-rule separators
- Add supported versions, the built-in mods, installation (Modrinth,
releases), network use (Mojang session sign-in; the access token never
reaches the Saturn server), building from source with submodules, and
a pointer to the version guide for multi-version changes
