Using texture minification filters
A Minification filter controls how a texture is interpolated when a scene
pixel maps to multiple texture pixels (texels)
FASTEST Use fastest method
NICEST Use best looking method
BASE_LEVEL_POINT Use nearest texel in level 0
map
BASE_LEVEL_LINEAR Bilinearly interpolate 4 nearest
texels in level 0 map
MULTI_LEVEL_POINT Use nearest texel in mip-mapped
maps
MULTI_LEVEL_LINEAR Bilinearly interpolate 4 nearest
texels in mip-mapped maps
