* janitor: Fix clippy error in textlayout.rs

* janitor: clippy fixes in inline_expressions.rs
Clippy claims the original code was slower and less clean, so let's

- We need to make sure that the initialization of global is in the right order.
- In C++ and rust, we need to add accessor to the global component
- There can be `PropertyReference::Global` in binding of globals
- The interpreter globals need to hold references to the global they may depend on
Fixes#175
