Sage Driver: Trilinear does not work on VSA-100 series, even when texture combining is disabled

[Frank Sapone]

As the title states. Just putting this here so we don't get forget about it.

In Mesa it checks for texture combining to be disabled and if its then it sets lodBlend and has a few special cases for locking and unlocking the TMUs appropriately during these states for X_MIPMAP_LINEAR. the functions that rely on grTexMipMapMode i.e setupTextureSingle will need a pointer passed to them when it's appropriate to set FXTRUE for lodBias instead of FXFALSE and then set the lock/unlock states for the multi-TMUs accordingly.
