Support for custom line caps?

[lellid]

Hi,
agg-sharp seems to be a great library!
I'm searching a OS agnostic library that can replace the Gdi+ that I'm using now. One reason I stayed for so long on Gdi+ is the need to draw other line caps than the usual ones, like arrows. Unfortunately, like all other OS agnostic libraries, agg-sharp does not seem to support such custom line caps. Is this a fundamental problem, or is it thinkable to implement such custom line caps?
