Leave the default values for OpenGL texture filters

The scaled wallpaper looks quite a bit better when linear texture
smoothing is applied, and I could not measure a significant difference
in framerate from setting the texture filter to GL_NEAREST. Hence it
seems not necessary to me to introduce the smoothing as an option.

The default value for GL_TEXTURE_MIN_FILTER is GL_NEAREST_MIPMAP_LINEAR
and the default for GL_TEXTURE_MAG_FILTER is GL_LINEAR. These make sure
that the texture is reasonably smoothed by using the weighted average of
the nearest four pixels.
