Best texture filter for "Crunchy Pixels" mode

[mhQuake]

The best texture filter for "Crunchy Pixels" mode is:

GL_TEXTURE_MIN_FILTER: GL_LINEAR_MIPMAP_LINEAR
GL_TEXTURE_MAG_FILTER: GL_NEAREST

This gives good visuals with both minifcation and magnification.

It's not possible to set this filter via the gl_texturemode command, but it is a valid filter, and it is exposed in D3D10+ hardware via the D3D10_FILTER_MIN_LINEAR_MAG_POINT_MIP_LINEAR filter mode, so we can be absolutely confident it also exists on any of the hardware Ironwail targets.

What's the best way to expose this via Ironwail?
