Build for Minecraft 26.3
Check / compile (pull_request) Successful in 16m19s

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.

Saturn Client is a free, open-source Minecraft client designed to enhance the gameplay experience while staying lightweight and customizable.
Our goal is to build a clean, optimized client that the community can contribute to and improve together.
Saturn runs on Fabric and supports **Minecraft 1.21.4 to 1.21.11, 26.1 and 26.2**, with one build per version (the 26.1 build also runs on 26.1.1 and 26.1.2). If something doesn't work on your version, please open an issue.

Every supported Minecraft version (1.21.4 to 1.21.11, and 26.1 to 26.3) builds from one copy of the version-specific code with [Stonecutter](https://stonecutter.kikugie.dev/):
- `common/`: all version-independent code (mods, UI, cosmetics, the server client). It has no Minecraft dependency and reaches the game only through the interfaces in `org.saturnclient.common`.
- `src/`: the version-specific code (providers, refs, mixins and the three mixin configs), one copy for every version. Where Minecraft's API differs between versions, the code goes behind version comments (see below).
@@ -18,7 +18,11 @@ Minecraft is obfuscated up to 1.21.11 and ships with Mojang's names from 26.1. T
Every version is built with Mojang's official names (`loom.officialMojangMappings()`), the names Minecraft itself ships from 26.1 on. Yarn isn't used any more: 1.21.11 has the last Yarn release.
Mojang renames things between versions. `src/` uses the active version's (1.21.11's) names, and `stonecutter.gradle.kts` lists replacements that swap in each version's name when Stonecutter processes it: for example `Identifier`, which was `ResourceLocation` before 1.21.11, `AvatarRenderState`, which was `PlayerRenderState` before 1.21.9, and `GuiGraphics`, which is `GuiGraphicsExtractor` from 26.1. Add a replacement there when a rename touches many lines. From 26.2 the open screen and overlay live on `Gui` rather than `Minecraft`, so code goes through `impl.ui.Screens` for them. A class that only moved package needs just a version comment on its import, and a renamed method a version comment where it's called.
Mojang renames things between versions. `src/` uses the active version's (1.21.11's) names, and `stonecutter.gradle.kts` lists replacements that swap in each version's name when Stonecutter processes it: for example `Identifier`, which was `ResourceLocation` before 1.21.11, `AvatarRenderState`, which was `PlayerRenderState` before 1.21.9, and `GuiGraphics`, which is `GuiGraphicsExtractor` from 26.1. Add a replacement there when a rename touches many lines, and only for a name that appears nowhere else in `src/`: replacements work both ways, so the new name is also turned back into the old one for older versions (a `mulPose`/`rotate` replacement would rename `MatrixStackRef.rotate` too). From 26.2 the open screen and overlay live on `Gui` rather than `Minecraft`, so code goes through `impl.ui.Screens` for them.
From 26.3 Minecraft uses SDL instead of GLFW, with SDL's numbers for keys (scancodes), modifiers and mouse buttons. Saturn keeps GLFW's numbers, which `common` uses and the config's keybinds store, and `impl.provider.Keys` converts at the boundary: key events and mouse buttons coming in, and key codes going to the game. Use `InputConstants`' key constants rather than GLFW's in version-specific code.
26.3 also compiles every shader through SPIR-V, so shader inputs and outputs need an explicit `layout(location = …)`. Saturn's `glass.fsh` is shared by every version from 1.21.6 and switches its layout with the defines `GlassRenderer` sets, as it already did for `HAS_LINE_WIDTH`. A class that only moved package needs just a version comment on its import, and a renamed method a version comment where it's called.
Released 1.21.x jars run on intermediary names (`method_1234`), not Mojang's, and Loom renames everything that refers to Minecraft when it builds them. So a mixin can't implement one of `common`'s Ref interfaces by relying on a vanilla method that happens to have the same name: the vanilla method is renamed in the jar, and the interface method is left without an implementation (`AbstractMethodError`). Shadow the vanilla method and implement the Ref method explicitly, as `WindowMixin` does. For the same reason, Ref methods mustn't share a name and parameters with a method of the class they're mixed into, or the mixin replaces the vanilla method in development.
