Modifying ProjectionDrawingStrategy [message #1052058]

I plan to use ProjectionAnnotations for hiding code, pretty similar as used for folding. However, such hidden code shall only be manipulated via dedicated context actions (not by clicking on it's +,- markers). In general, the projection viewer shall hide hidden code's existence completely.

Disabling the paint() method for the annotation marker (left ruler) is simple, but how can I manage to also hide the first line of the hidden ("folded") content, including the rectangle with the two dots at the end of the folded line?

As fas as I'm aware of ProjectionDrawingStrategy is an inner class of ProjectionSupport which is not intended to be overridden.

I just realized that ProjectSupport allows to set my own AnnotationPainterDrawingStrategy. A good point to start with.

Combined with an overridden ProjectionPosition (computeProjectionRegions()), that should do the job, i.e., allow me
- to get rid of the fancy annotation rectangle [..] as well as
- to completely hide the "folded" (hidden) code.
