r1gl anisotropic bug

[starttimartti]

I take it that gl_ext_texture_filter_anisotropic should enable/disable anisotropic filtering and gl_ext_max_anisotropy just defines the amount of filtering. Currently gl_ext_texture_filter_anisotropic doesn't seem to do anything, and if I want to disable anisotropic filtering I have to set gl_ext_max_anisotropy to 1 (it even defaults to 2).
