The statistics are updated in the generic codepath, which is not used by
RageDisplay_Legacy::DrawLineStripInternal() when rendering smooth lines.
Note, that the output vertex count can differ a lot between smooth lines
(2) and non-smooth lines (~38 output vertices per input vertex), so
updating the statistics can not be done in RageDisplay::DrawLineStrip()
like it is donw for the other draw functions.
The IsUsingWideScreen() function only checked 16:10 and 16:9, now we just
check that the ratio is greater than 16:10. (Coincidentally that's also
what the documentation states about this function.)
