When I was building Geany on my 1.5GHz PowerBook G4, the performance was 
very poor. Meanwhile, the performance of Gedit was more acceptable. 
Komodo had similar performance issues, and that was an OS X "native" 
build of Scintilla. (I'm not sure if Scintilla uses the Carbon or Cocoa 
API on OS X; probably Carbon.)

That's not to say Scintilla is inherently slower than GtkSourceView, but 
there was noticeable difference back then.

I think it would be an interesting idea to at least try out. I like the 
sound of mixing languages with GtkSourceView. For example, PHP + HTML + 
JavaScript + CSS = clear winner. This feature has been on Scintilla's 
radar for quite a while, but not much has happened with it yet. (To be 
fair, Scintilla's PHP lexer is also its HTML lexer.)

Speaking of changing the text editor widget, maybe one day Geany will be 
able to use Bespin! (Just a joke. But MVS separation would allow for 
something as crazy as that.)
