We discussed on IRC earlier this week, below the log for reference -
did that solve the question for you?

 chris_wot: thorsten! hey, can you help me out?
 chris_wot: do you know what does line mitering?
 chris_wot: is it in basegfx?
 quikee[m]: the vcl polyline accepts miter limit as an parameter
 thorsten: yep, fwict the method noelgrandin gave does that
 ***chris_wot relooks at the code
 chris_wot: you mean basegfx/source/polygon/b2dlinegeometry.cxx ?
 thorsten: yep
 chris_wot: thorsten how do I set the miter limit though?
 thorsten: chris_wot: see vcl/headless/svpgdi.cxx:    // convert miter minimum angle to miter limit for how to convert between the two related ways to express that
 chris_wot: legend
 chris_wot: thorsten is it the line double fMiterLimit = 1.0 / sin( fMiterMinimumAngle / 2.0);
 chris_wot: as I want to do this indepently of the angle
 chris_wot: which is what SETMITERLIMIT does...
 chris_wot: thorsten something like this - https://www.partnersoftware.com/documentation/MP/v4.5.26/mp_wblegendlinestylemiterlimit.png
 thorsten: chris_wot: indeed, that's the concept

Cheers,

-- Thorsten
