Subject: [PATCH] wxCarioContext:Flush now draws back to the QT image

wxCairoContext::Flush was flushing back to the internal image but this
image wasn't drawn back to the QPainter until the wxCarioContext
instance was destroyed.

This fix ensure that after a call to Flush, anything drawn by Cario is
drawn back to the QImage.

Closes https://github.com/wxWidgets/wxWidgets/pull/1068
