If someone does this...
canvas.drawString(x, y, 'some text with RTL and maybe LTR')
textObject.textout('some RTL text')
...should we magically intercept it and reverse when pyfribidi2 is
available? Or should we leave it to the programmer?
I haven't done any benchmarking but I would imagine that once you are
dealing with Unicode text, passing it through the C-based log2vis
function will be pretty quick and will return LTR text unchanged.
We'll do some experiments this week to see if there is a measurable
performance hit. Can anyone see any downside to doing this
