1.21.4 and 1.21.5 read every shader's imports while loading resources,
and dynamictransforms.glsl only exists from 1.21.6, so resources failed
to load there. The glass shader declares the transforms block itself
again, with LineWidth behind a define the pipeline sets before 1.21.11.

1.21.6 to 1.21.10 draw glass as 1.21.11 does, without samplers, and the
glass shader imports vanilla's transforms block, whose layout differs
between them. 1.21.4 and 1.21.5 draw straight into the framebuffer,
so the game is saved before the screen blurs it, and glass is a render
layer: with a pipeline on 1.21.5 and a shader program on 1.21.4.

A copy of the game behind the screen is blurred once a frame and drawn
through each panel's rounded rectangle texture by a glass pipeline.
Older versions keep blurring the whole background.

NametagsMixin hooked EntityRenderer.renderLabelIfPresent with a
VertexConsumerProvider, which 1.21.9 moved to the render command queue, so
custom nametags only worked before 1.21.9 (#30).
LivingEntityRendererMixin already captures health and entity type at the
end of LivingEntityRenderer.updateRenderState. It now also applies
NametagsMod's replacement to state.displayName there, the label the
renderer draws later. This works the same on every version, so
NametagsMixin and its features.mixins.json entry are gone.
As before, only entities that already show a label get a replacement. For
players, the role icon is added after this (PlayerEntityRendererMixin), so
it now comes before the replaced name and keeps its colour, instead of
being folded into the replacement text.

1.21.5 is the first version before the 1.21.6 GUI rewrite, which moved
GUI drawing from vertex consumers and a MatrixStack to render states and
a 2D Matrix3x2fStack.
- RenderScopeImpl and EntityDrawerImpl have two whole implementations,
one per side of 1.21.6 (a single >=1.21.6 / else split), instead of
conditionals scattered through them. Callers use RenderScopeImpl(context)
in every version; 1.21.5's did the same thing through its
(matrices, vertexConsumers) constructor.
- MatrixStackMixin (MatrixStack as a MatrixStackRef) is real before 1.21.6
and empty from 1.21.6, registered everywhere like NametagsMixin.
- DrawContextAccessor exposes the vertex consumers before 1.21.6 and the
GUI render state from it.
- Smaller changes: fog (BackgroundRenderer vs FogRenderer), the end
portal texture arguments (ShaderUtils, now a flat three-way chain), the
status effect sprite manager, and getIconId only from 1.21.6.
Features 1.21.6+ lacks stay on 1.21.5, with a TODO: the title panorama
behind Saturn screens and the background blur (screen.backgroundBlur,
see #23).
The 1.21.5 jar differs from the old one only in the helpers from earlier
steps, the RenderScopeImpl(context) calls, the empty SaturnRenderState
and unused Matrix3x2fStackRef, and 1.21.5's dead NameTagMixin (never
registered) being gone. 1.21.6-1.21.11 only gain the empty
MatrixStackMixin and its impl.mixins.json entry.

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.

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.
