[fpc-pascal] Using include files in code tools

[Ryan Joseph]

When using code tools I've found that it needs to start from a main unit (otherwise other relevant macros may not be set) and then insert includes into the source text. This is fine but when I inspect the node tree (TCodeTreeNode) how do I know which include a node came from?

I need this information so I can get navigate to the include file AND relative text offset into the include file text.
