    compositor: Fix GL texture filter
    
    Bug: 15676
    
    Between versions 4.13.1 and 4.13.2 the GL_NEAREST filter (used on the
    deepest levels of desktop zoom) stopped working, and GL_LINEAR was
    used instead. Fix by setting GL_TEXTURE_MIN_FILTER in addition to
    GL_TEXTURE_MAG_FILTER, like was done in version 4.13.1; apparently the
    former needs to be correctly configured for the latter to take effect.
