Another update, I guess I love to talk to myself.
I got the drawing part done as follows:
CALayer *aLayer = [CALayer layer];
NSRect r = [self.layoutManager boundingRectForGlyphRange: aRange
inTextContainer: self.textContainer];
aLayer.backgroundColor = CGColorCreateGenericRGB (0.2, 0.2, 0.2, 0.2);
// obviously this will be changed to something nicer
aLayer.frame = r;
aLayer.cornerRadius = 6.0f;
[self.layer addSublayer: aLayer];
There are two problems:
1. the y-location of the layer that is drawn is wrong, I think it has to do
with the coordinates being flipped
2. when the range contains a line break, I get the rect for two whole lines,
not just the glyphs.
