Detailed Description

An arbitrary named shader uniform (name → float / vec2 / vec3 / vec4).

Lets a custom post-effect (save_layer_with_sksl_post_effect) accept any uniform its shader declares, not just the fixed widget vocabulary above — the difference between a real user-facing shader-effect API and a toy. count selects the arity (1..4); only that many of v are read. Bound via SkRuntimeEffectBuilder::uniform(name) guarded by findUniform, so names the shader doesn't declare are ignored.
