Overview

sfEvent is a C union. The largest variant (KeyEvent on x86_64: 4+4+4+4

20 bytes) defines the union size; we allocate a buffer that big and

reinterpret per-type. We use a Struct (not Union) here because Ruby FFI handles variable-tag unions awkwardly — the tag is the first int32 in every variant, so we read it directly.
