Texture Sharpening

[Disciple-X]

For people who want to make detailed wad projects on lesser machines, something to sharpen the OpenGL smoothed textures could help details a lot. I am not talking about "detail textures" like the Unreal engines use, just a simple option to sharpen up smoothed textures when in OpenGL. using a double-linear mip option is one way, but then textures are blocky up close. The smoothness of OpenGL is great for large textures, but a lot of wad makers want to make a cross-port wad that can function on many other ports, so they stick with basic Doom texture dimensions.

The only algorithms I have seen offer bad quality and eat up a lot of processing time. And one of them (hq2x/4x) is GPL so I can't use it anyway.
