Summary: Aspect ratio

Initial Comment:
Most screens run with a 4/3 aspect ratio (800×600,
1024×768, 1600×1200...). Most SCUMM games use a 85/
aspect ratio (320×200). A video mode that resize on the
fly would be welcome.

Sorry to answer late like this: I did not have a good enough
network connection for two weeks.

Yes, stretching vertically (or horizontally, in fact
stretching _differently_ horizontally and vertically) is
what I beg for.

Yes, on low resolution, it is ugly not to have all pixels
scaled the same amount. But it is also ugly to have graphics
designed for 1×1.2 pixels displayed with square pixels. As a
matter of facts, I think that which one is more ugly is a
question of taste.
(and on my screen, the full-screen 640×480 is achived by
doubling one pixel out of four to reach 800×600, without
antialiasing, so I have _both_ disadvantages :-( )

You are right, the GL back-end does that very good. But how
slow is it on my `old' laptop... :( I do not think that the
non-homogenous antialiased scaling is itself so time
consuming, so I would like it in the fast SDL back-end.

PS: happy new year.

What exactly is it that you are requesting? Do you want us
to distort the displayed data, i.e. stretch it vertically?
But why?! IMHO that looks extremly ugly.
The SDL_GL backend still allows it, though. You can switch
it between displaying black borders at the top/bottom and
stretching.
For the normal SDL backend, we just request a surface of
640x400 pixel. At least over here, that's mapped to 640x480
mode, and SDL automatically ensures we are displaying
centered on that display. If that is not the case on your
system, please provide some more details as to what you
want, exactly.
