It should hopefully be done for 3.6.12 final. If not, 3.7 is actually not that far away.
I hope that the rewrite will allow for more intelligent scaling, if not, I will see about adding that in.
Oh, and for the most part, the original art is not scaled in any way for 1024x768.
It could perhaps be an option to do this if there is no 1024x768 art is a good idea. Main reason is the mainhall. (In FSPort at least)
On 1280x1024, the mainhall would look much better if scaled in-engine from 640x480 instead of using custom graphics already scaled. This is because 1280x1024 is roughly a clean scale (2x) as compared to scaling from the already scaled to 1024x768 art.
However, in the case that 1024x768 art is present, it should indeed be used. This applies to FS2, since it has actual high-res mainhall animations that weren't scaled. FS1's isn't.
If this actually gets in, the 2_***** .anis for FSPort should be taken out, since it is highly unlikely someone will re-make those. Perhaps for the HUD as well, but it is much easier to replace them (as I am) then it is to do for the mainhall.
Basically, things could be done by this in intelligent scaling:
Allow high-res art to be used in specified resolutions. For example, using, say, 800x600 instead of 1024x768.
Also the option to scale or letterbox low-res graphics if there are no high-res graphics present (Useful for mainhalls such as FS1).
This should be settable differently for HUD and the mainhall. For example, using an unscaled hud from 640x480 may look better in 800x600 than a scaled one. The size difference would likely be negligible.
Also, I knew the hud head1 was just a border. What I meant was if it used 2_head1, then the actual head anis for comm would be too small and not fill the box (unless they are scaled in-game)
