Description Tom Hofmann

3.2 RC3

IBeam decorations are not draw at the end of the file.

Steps:
- create an empty Java file
- type '"' -> the linked mode exit position should be drawn after the closing quote, but it is not

Reason: AnnotationPainter filters decorations that do not overlap with the range being redrawn. Since an IBeam decoration is drawn on the character region following the offset, which is after the document extent in this case, it is optimized away.

Fix (see also patch): The overlap predicates in AnnotationPainter should consider and document ranges as overlapping that truly overlap with *or touch* each other. This way, an IBeam decoration right at the end offset of the redraw range would still be considered.

Fixes the painting of IBeams at the document end.

Not a 3.2 issue, as typing at the document end is not a very likely operation and the consequences of extending the overlap predicates are not overseeable.
