Subject: [PATCH] osc.lua: add option to make rendering smoother

OSC rendering used to be smooth (up to OSD rendering fps) before
48f906249ef359c66fc6c5bf4cc5885c8293bf8e, but after that commit the
frame duration is hardcoded to 30 ms. This is too high and results in
choppy OSC rendering, which is very noticeable with the progress bar
while moving mouse over it or playing a short 60 fps video.

This makes the duration an option so that it can be decreased to make
OSC rendering smoother.
