When you have bracket highlighting on, and it highlights beginning or ending
braces and parentheses in the Java editor, what is the actual editor plug-in
doing to perform the highlighting (not the JavaPairMatcher, since that's
only locating the braces), i.e. is it some widget or graphic tool thing to
make the box outline appear, and if so how could I employ this or something
similar to it for a different purpose?

I wrote an editor where i define my bracket highliting,
you need a MatchingCharacterPainter and you have to implement
a class : SomePairMatcher implements ICharacterPairMatcher
where you say what you want to match with highlighting.
Here is an example :
public class SomeEditor extends TextEditor {
protected PaintManager fPaintManager;
protected MatchingCharacterPainter fBracketPainter;
protected boolean isBracketHighlightingEnabled() {
return true;
}
private void startBracketHighlighting() {
if (fBracketPainter == null) {
fBracketPainter = new
MatchingCharacterPainter(fSourceViewer,new SomePairMatcher());
fBracketPainter.setColor(new Color(Display.getCurrent(), new RGB(
127, 0, 85)));
fPaintManager.addPainter(fBracketPainter);
}
}
protected void createActions() {
super.createActions();
.......
fPaintManager = new PaintManager(fSource);
if (isBracketHighlightingEnabled()) {
startBracketHighlighting();
}
......
}
private void stopBracketHighlighting() {
if (fBracketPainter != null) {
fPaintManager.removePainter(fBracketPainter);
fBracketPainter.deactivate(true);
fBracketPainter.dispose();
fBracketPainter = null;
}
}
and it works.

Would something like this work if I wanted to just highlight different
things? I.e. I don't want to do any pair anything highlighting, I just want
a way to change graphical appearances around characters and such without
affecting the code itself, and the bracket highlighting seems to relate to
that. I wanted to know if there's something (JFace, SWT, etc) that has
different editor window effects.

You could use Annotations - this is what's used to do the occurrences
highlighting and linked editing boxes.
See the org.eclipse.ui.editors.markerAnnotationSpecification extension
point to see how to contribute custom annotations.
