Software vs GLQuake: Non-square pixels

Welcome to a rather short part of the Software vs GLQuake series. It came up at func so I quickly wrote it.

Lava_Croft once taught me about another quite nasty and overlooked regression in most GL engines. Textures that are not sized in a power of two (64, 128, 256 etc) are getting rescaled. And with that the pixels are not square anymore but a huge mess of distorted uglyness. This is most easily seen on a weapon skin so I used that in the image below. The Shambler’s face also is a good place to spot it. On the left is software Quake (argh, Argh, ARGH! The high FOV is to blame for that, sorry.), in the middle a bad GL engine and on the right a good one. From what I know at least Fitzquake (of course!) and Darkplaces fixed this.

    It’s also very noticeable in the Help screens.
