annoying E effects on horizontally moving items

[Schuett Thomas <Thomas.Schuett@icn.siemens.de>]

Hello,

I had an idea about how to get rid of 
the anoying E effects on horizontally moving items:

on a-halfpicture do:
  - write an interpolation between previously stored a-halfpicture
    and recent a-halfpicture to a-lines on graphics card
  - store recent a-halfpicture for later use
  - write b-halfpicture (was previously stored) to b-lines on graphics card

on b-halfpicture do:
  - write an interpolation between previously stored b-halfpicture
    and recent b-halfpicture to b-lines on graphics card
  - store recent b-halfpicture for later use
  - write a-halfpicture (was previously stored) to a-lines on graphics card

=> Each halfpicture would be changed all 1/50 sec. (not only all 1/25).

=> On still pictures, an interpolation between previous a-halfpicture with
     recent a-halfpicture would be the same as recent and the same as
     previous a-halfpicture. (same true for b-halfpicture). 
     So still pictures would look exactly the same as without this algorithm.

Is it possible to introduce such an algorithm, or would it cost to much CPU or
maybe just don't fit into the hardware architecture or so?

cu,
