[Mesa-dev] [PATCH 30/30] mesa/st: require linear interpolation for ARB_texture_float

[Erik Faye-Lund]

There's nothing in the ARB_texture_float specification that limits
filterability for floating-point textures, so we need to ensure that
this is required to enable this extension. Luckily, we have just the
right bits ready.
