[fixed] Screwed up aspect ratio correction for 5:4 screens

This stems off of this topic at Doomworld:

Basically, the problem is that when you turn on 5:4 correction, GZDoom squashes the display in the wrong direction, thus making the problem worse, instead of fixing it.


GZDoom, 720*576 (lowest 5:4 there is), no correction:

Turning on 5:4 correction.... [angry_nintendo_nerd]Well, that really accomplished a lot![/angry_nintendo_nerd]:

And there you have it.

Yes i also noticed this, ZDoom squeezes the image down, and shows a little more in the top and bottom, GZDoom stretches the image upwards making everything look too thin

[lemonzest]

will this need fixing in zdoom or is it a purely gzdoom thing?

It was a GZDoom only problem. The aspect ratio information for the software renderer was not suitable for OpenGL.

Glad to see you were able to fix it. Thanks a ton, Graf.

The aspect ratio information for the software renderer was not suitable for OpenGL.

Strange that it would make it do that, though. Seems like it would just not do anything then, or garble the screen up... Heh, goes to show you how much I know about these things.

I have absolutely no idea how the software renderer is getting the correct ratio from the values stored for 5:4. In the end it was easiest for me to create a new table with the correct aspect ratios.
