LibGL: Fix interpretation of mipmap filtering modes

Browse source 
GL_LINEAR_MIPMAP_NEAREST means choose nearest mipmap level, interpolate
texels linearly.

GL_NEAREST_MIPMAP_LINEAR means choose the two closest mipmap levels,
sample the texels unfiltered and linearly interpolate based on the
fractional value of the mipmap level.

Previously we had this backwards.
