Change default value of texture filtering mode setting

[granis48]

What feature is your improvement idea related to?

The game says the recommended setting for Texture Filtering Mode is Trilinear, this is extremely low and actually does affect elements of some maps in the game, e.g. surf_illusion stage 3-4 uses texture mipmaps to do a cool effect for the geometry.

Describe the solution you'd like

Set the default value for Texture Filtering Mode to Anisotropic 16x, for the majority of players this shouldn't have any noticeable impact on performance.
(Anyone who sets everything to lowest setting for "that extra juice" deserves this worse experience)

Additional context

Here is the start of surf_illusion stage 3 on Anisotropic 16x (presumably as intended by mapper):

Here it is on Bilinear:

As you can see this can potentially give players a worse experience on some maps.
Game resolution and fov_desired also affect this problem but thats not really something you can fix or easily communicate to players. The screenshots are taken in 1080p on default fov

The default GPU settings are pretty whack, because the moddefaults.txt file, which contains default/recommended settings for individual gpus, is hopelessly outdated (the newest GPUs it has are from ~2011). So when it encounters any newer gpu, it defaults to unknown one from that brand and picks pretty whack settings. This can also be seen when booting game for the first time on system.

Sounds like it shouldn't be super hard to change the defaults for the known brands then, unless we're talking individual models as well....
Either way might wanna change how it picks the default at some point

It has default settings for about 854 different GPUs from all 3 vendors. Starting from somewhere 2003-2004.
