#337 Progressive scan (flicker fix) for interlaced modes

[MIRKOSOFT]

Hi!

I used first time VICE for displaying C128 VDC interlaced modes and they're supported.
Wow!
Then I tested also C64 not real interlaced modes (resolution is the same) and also VIC-II TriLace, works.
I found problem only with TED interlaced modes.

First what we can see is flickering, of course it is standard behavior of interlaced modes for swapping even and odd fields.
But when I work in Z64K or Kernal64 - there it has deinterlacing option and flickering is fixed.
Here's question what I mean deinterlacing...
I mean that deinterlacing is using progressive scan - so flickerfix.
Yes, for this needs computer extra hardware - flickerfixer.
VICE supports no one and I think it will maybe never.
Why flicker fixing?
We all love not flickering picture. If you want to argument with that's not real, it hepls at least to create screenshot.
Real interlace modes has C128 by both chips - VDC and VIC-IIe.
We know that VIC-II in C64 features not interlacing - so fake interlaced modes (please don't crucify me for naming them so - I know that these modes allows C64 to get more colors and many really cool effets)
TED features interlacing, in VICE not yet emulated C65 features interlacing too.
I hope this ticket will be accepted as valid. Think about.
