[news.eclipse.platform.rcp] Update editor coloring according to folding

[Michael Spector <michael@xxxxxxxx>]

Hi!

I have the following problem: it doesn't matter whether editor elements 
are folded or not coloring remains the same. When everything is unfolded 
 the coloring is correct, but when folding one of elements it looks 
like previous coloring retains in folded element. I use line style 
provider, which executes scanner on document contents, and produces 
StyleRange's that contain coloring information correct for the document 
contents.
The question is: what part should be responsible for reconciling editor 
coloring according to the projection model?

Thanks!
