Any reason why are you creating a new pen in GdipDrawRectangleI, and while using an existing one in GdipDrawLineI?

Yes, the reason for that is the passed pen can have any endcap style, but to draw the rectangle the pen needs square endcaps. The same does not apply to DrawLine.
Do you have a confirmation that native gdiplus does that as well? +relay,+snoop trace, some other test?
