EventList and Spline do not seem to be defined (api)

从 tools/gen_api.js 以及 EventList 和 Spline 的 blocklist 条目开始，然后检查 build/_deps/raylib-src/parser/output/raylib_api.json 和生成的 tools/api.json。将生成的声明与 DLL FFI wrapper 使用的 raylib 版本进行比较。当受影响的 API 条目与可用的 raylib 符号匹配，并且不再产生未定义函数错误时，即表示完成。

Essentially, all the functions with EventList or Spline are not defined (but are output by raylib api-gen) and throw an error if DLL is ffi-wrapped.

I think this is related to versioning mismatch with raylib (which may be a sign I need to adjust build to use raylib better.)

  let paramPointer = false

    if (/[A-Z]/.test(p.type)) {
      paramPointer = true
      break
