This should work, but only if you remembered to do [self lockFocus] and
[self unlockFocus] around your drawing. (Assuming, that is, that
you're drawing in the view that received the -mouseDragged: message.)
After reading the docs the only way I can see of changing this is to
just make a portion of the view dirty and then run through the array
calculating whether that line is affected and if so redraw it.
This shouldn't actually be very difficult, because you can just ask for
[bezierPath bounds] and see if that intersects with the dirty region.
Kind regards,
Alastair.
