I saw some comparisons (apologize, I cannot cite from my brain's memory),
showing that GDI+ is not that fast as it might be expected and is a real
pain in the ass due to its license terms and conditions disallowing open us=
e
of even headers files. Author mentioned that newest cairo is faster. SFML
metioned ealier in this thread is REALLY fast according to what I've read,
but not used by default in any of known GUI "environments" - but supports
wxWidgets and Qt well.
