[Lazarus] Regex and Syntax Highlighting

[Zaher Dirkey]

I beleave regex is not a good choice.
If you compare the speed you will find SynEdit is more faster.
I import it to make my syntax for my site using PHP i found my Highlighter
is more faster (10 time) than the famous one (Geshi) that use the regex.
