Function documentation

static bool ShaderCompiler::Essl100Emitter::Transform(StringView modernSource, bool vertexStage, String& out, Diagnostic& diag)

Transforms modernSource (as produced by ShaderParser::BuildStageSource) into ESSL 100, writing the result to out. vertexStage selects the vertex-vs-fragment lowering. Returns false and fills diag (with the offending line) when the source uses a feature ES2 cannot express — a "layout(std140)" uniform block or gl_VertexID — which this emitter does not attempt (see the file comment).
