There is code for use with regions, how ever it currently has a bug where only the hash is colored, additionally it does not appear that inside `gml_string_hint_locals_hint_locals_pre` the `#region <comment>` is not accounted for when using such syntax as: `#region Example`

Fixed this in the new version - it was the parser not updating the position after it reads the #region line. gml_string_hint_locals functions are for things that change based on code contents - like local variables or macros.
