LibGL: Implement gl_tex_parameterfv

Browse source 
This is the vectorized version of `gl_tex_parameter`, which sets the
parameters of a texture's sampler. We currently only support one single
pname, `GL_TEXTURE_BORDER_COLOR`, which sets the border color of a texel
for if it is sampled outside of a mip-map's range.
