I’d like to make arrow tips in TikZ that match with xy-pic’s standard arrowheads. The methods from this similar question look appropriate, but I thought I’d check first: has anyone else already created these?
(The motivation is mainly that I’d like to have TikZ and xy-pic diagrams coexisting in the same document, since I often want the flexibility of TikZ, but I have co-authors who don’t know it and prefer to write in xy-pic.)
